::stage egg:: eggs are laid by female birds in clutches ranging in number from just 1 for condors to as many as 17 for the grey partridge. Eggs are incubated by one or both parents for a period of time until the embryo inside has developed into a chick which is ready to hatch. A chick may have to work for hours or even days to break through the shell of its egg. Most birds have a small bump near the tip of their beak called an egg tooth to help them hatch. ::stage hatchling:: a hatchling is a bird that has just hatched and may be almost completely naked apart from some fine down. Hatchlings eyes may not open and it is unlikely to be able to care for itself. The term hatchling is usually used to refer to altricial chicks which are undeveloped and unable to move around. Hatchlings will stay in the nest for some time and will rely on their parents for feeding and to keep them warm. Precocial birds such as ducks and owls are relatively mature when they are born and are sometimes able to feed themselves and leave the nest soon after. ::stage nestling:: nestlings are chicks that are a few days old and are covered in soft down. There may be signs of flight feathers and nestlings eyes may have opened but they will be unable to leave the nest and will still rely on their parents for food and warmth. ::stage fledgling:: chicks that have developed flight feathers and wing muscles are known as fledglings. fledglings will have started to explore outside the nest but will still be under the care of their parents. Fledglings are fairly awkward and only able to fly for short distances but will be active and able to hop about. The length of time it takes for a chick to fledge varies between species. For example it takes 6 months before the chicks of the great frigatebird fledge and their parents feed them for a further 14 months. ::stage juvenile:: a juvenile bird is at the awkward teenage stage of being a bird. Juvenile birds will have left the nest and will be fully independent. juvenile bird will be in their first plumage and can look similar to adult birds although they may be duller with less defined markings. Out in the field it can be difficult to identify a juvenile bird and for most species of birds the length of time they are a juvenile is very short. ::stage subadult:: subadult birds are young birds that are older than juveniles but have still not developed adult plumage and are not sexually mature. Some birds such as house sparrows will become sexually mature at just a few months whereas larger birds such as golden eagles won't become sexually mature until they are 4 or 5 years old. The terms immature and subadult are interchangeable by many ornithologists although immature can be used to refer to any bird that isn't an adult. ::stage adult:: adult birds are sexually mature and are able to reproduce. adult birds will be in full adult plumage which may change depending on the season. Some birds have brighter plumage with clearer markings when in breeding season while in other birds, such as puffins, the shape and colour of their bills may change. | 6 months long does it take a golden eagle to be sexually mature. | not_entailment | lookup |

::stage egg:: eggs are laid by female birds in clutches ranging in number from just 1 for condors to as many as 17 for the grey partridge. Eggs are incubated by one or both parents for a period of time until the embryo inside has developed into a chick which is ready to hatch. A chick may have to work for hours or even days to break through the shell of its egg. Most birds have a small bump near the tip of their beak called an egg tooth to help them hatch. ::stage hatchling:: a hatchling is a bird that has just hatched and may be almost completely naked apart from some fine down. Hatchlings eyes may not open and it is unlikely to be able to care for itself. The term hatchling is usually used to refer to altricial chicks which are undeveloped and unable to move around. Hatchlings will stay in the nest for some time and will rely on their parents for feeding and to keep them warm.

Most birds have a small bump near the tip of their beak called an egg tooth to help them hatch. ::stage hatchling:: a hatchling is a bird that has just hatched and may be almost completely naked apart from some fine down. Hatchlings eyes may not open and it is unlikely to be able to care for itself. The term hatchling is usually used to refer to altricial chicks which are undeveloped and unable to move around. Hatchlings will stay in the nest for some time and will rely on their parents for feeding and to keep them warm. Precocial birds such as ducks and owls are relatively mature when they are born and are sometimes able to feed themselves and leave the nest soon after. ::stage nestling:: nestlings are chicks that are a few days old and are covered in soft down. There may be signs of flight feathers and nestlings eyes may have opened but they will be unable to leave the nest and will still rely on their parents for food and warmth. ::stage fledgling:: chicks that have developed flight feathers and wing muscles are known as fledglings. fledglings will have started to explore outside the nest but will still be under the care of their parents. Fledglings are fairly awkward and only able to fly for short distances but will be active and able to hop about. The length of time it takes for a chick to fledge varies between species. For example it takes 6 months before the chicks of the great frigatebird fledge and their parents feed them for a further 14 months. ::stage juvenile:: a juvenile bird is at the awkward teenage stage of being a bird. Juvenile birds will have left the nest and will be fully independent. juvenile bird will be in their first plumage and can look similar to adult birds although they may be duller with less defined markings. Out in the field it can be difficult to identify a juvenile bird and for most species of birds the length of time they are a juvenile is very short. ::stage subadult:: subadult birds are young birds that are older than juveniles but have still not developed adult plumage and are not sexually mature. Some birds such as house sparrows will become sexually mature at just a few months whereas larger birds such as golden eagles won't become sexually mature until they are 4 or 5 years old. The terms immature and subadult are interchangeable by many ornithologists although immature can be used to refer to any bird that isn't an adult. ::stage adult:: adult birds are sexually mature and are able to reproduce. adult birds will be in full adult plumage which may change depending on the season. Some birds have brighter plumage with clearer markings when in breeding season while in other birds, such as puffins, the shape and colour of their bills may change. | Fledgling stage do baby birds develop flight feathers. | entailment | lookup |
::stage egg:: eggs are laid by female birds in clutches ranging in number from just 1 for condors to as many as 17 for the grey partridge.

The terms immature and subadult are interchangeable by many ornithologists although immature can be used to refer to any bird that isn't an adult. ::stage adult:: adult birds are sexually mature and are able to reproduce. adult birds will be in full adult plumage which may change depending on the season.

::stage egg:: eggs are laid by female birds in clutches ranging in number from just 1 for condors to as many as 17 for the grey partridge. Eggs are incubated by one or both parents for a period of time until the embryo inside has developed into a chick which is ready to hatch. A chick may have to work for hours or even days to break through the shell of its egg. Most birds have a small bump near the tip of their beak called an egg tooth to help them hatch. ::stage hatchling:: a hatchling is a bird that has just hatched and may be almost completely naked apart from some fine down. Hatchlings eyes may not open and it is unlikely to be able to care for itself. The term hatchling is usually used to refer to altricial chicks which are undeveloped and unable to move around. Hatchlings will stay in the nest for some time and will rely on their parents for feeding and to keep them warm. Precocial birds such as ducks and owls are relatively mature when they are born and are sometimes able to feed themselves and leave the nest soon after. ::stage nestling:: nestlings are chicks that are a few days old and are covered in soft down. There may be signs of flight feathers and nestlings eyes may have opened but they will be unable to leave the nest and will still rely on their parents for food and warmth. ::stage fledgling:: chicks that have developed flight feathers and wing muscles are known as fledglings. fledglings will have started to explore outside the nest but will still be under the care of their parents. Fledglings are fairly awkward and only able to fly for short distances but will be active and able to hop about. The length of time it takes for a chick to fledge varies between species. For example it takes 6 months before the chicks of the great frigatebird fledge and their parents feed them for a further 14 months. ::stage juvenile:: a juvenile bird is at the awkward teenage stage of being a bird.

There may be signs of flight feathers and nestlings eyes may have opened but they will be unable to leave the nest and will still rely on their parents for food and warmth. ::stage fledgling:: chicks that have developed flight feathers and wing muscles are known as fledglings. fledglings will have started to explore outside the nest but will still be under the care of their parents. Fledglings are fairly awkward and only able to fly for short distances but will be active and able to hop about. The length of time it takes for a chick to fledge varies between species. For example it takes 6 months before the chicks of the great frigatebird fledge and their parents feed them for a further 14 months. ::stage juvenile:: a juvenile bird is at the awkward teenage stage of being a bird.

Some birds such as house sparrows will become sexually mature at just a few months whereas larger birds such as golden eagles won't become sexually mature until they are 4 or 5 years old. The terms immature and subadult are interchangeable by many ornithologists although immature can be used to refer to any bird that isn't an adult. ::stage adult:: adult birds are sexually mature and are able to reproduce. adult birds will be in full adult plumage which may change depending on the season.

::stage egg:: eggs are laid by female birds in clutches ranging in number from just 1 for condors to as many as 17 for the grey partridge. Eggs are incubated by one or both parents for a period of time until the embryo inside has developed into a chick which is ready to hatch. A chick may have to work for hours or even days to break through the shell of its egg.

::stage egg:: eggs are laid by female birds in clutches ranging in number from just 1 for condors to as many as 17 for the grey partridge. Eggs are incubated by one or both parents for a period of time until the embryo inside has developed into a chick which is ready to hatch. A chick may have to work for hours or even days to break through the shell of its egg. Most birds have a small bump near the tip of their beak called an egg tooth to help them hatch. ::stage hatchling:: a hatchling is a bird that has just hatched and may be almost completely naked apart from some fine down. Hatchlings eyes may not open and it is unlikely to be able to care for itself. The term hatchling is usually used to refer to altricial chicks which are undeveloped and unable to move around. Hatchlings will stay in the nest for some time and will rely on their parents for feeding and to keep them warm. Precocial birds such as ducks and owls are relatively mature when they are born and are sometimes able to feed themselves and leave the nest soon after. ::stage nestling:: nestlings are chicks that are a few days old and are covered in soft down. There may be signs of flight feathers and nestlings eyes may have opened but they will be unable to leave the nest and will still rely on their parents for food and warmth. ::stage fledgling:: chicks that have developed flight feathers and wing muscles are known as fledglings. fledglings will have started to explore outside the nest but will still be under the care of their parents. Fledglings are fairly awkward and only able to fly for short distances but will be active and able to hop about. The length of time it takes for a chick to fledge varies between species. For example it takes 6 months before the chicks of the great frigatebird fledge and their parents feed them for a further 14 months. ::stage juvenile:: a juvenile bird is at the awkward teenage stage of being a bird. Juvenile birds will have left the nest and will be fully independent. juvenile bird will be in their first plumage and can look similar to adult birds although they may be duller with less defined markings.

There may be signs of flight feathers and nestlings eyes may have opened but they will be unable to leave the nest and will still rely on their parents for food and warmth. ::stage fledgling:: chicks that have developed flight feathers and wing muscles are known as fledglings. fledglings will have started to explore outside the nest but will still be under the care of their parents. Fledglings are fairly awkward and only able to fly for short distances but will be active and able to hop about. The length of time it takes for a chick to fledge varies between species. For example it takes 6 months before the chicks of the great frigatebird fledge and their parents feed them for a further 14 months. ::stage juvenile:: a juvenile bird is at the awkward teenage stage of being a bird. Juvenile birds will have left the nest and will be fully independent. juvenile bird will be in their first plumage and can look similar to adult birds although they may be duller with less defined markings.

Some birds such as house sparrows will become sexually mature at just a few months whereas larger birds such as golden eagles won't become sexually mature until they are 4 or 5 years old. The terms immature and subadult are interchangeable by many ornithologists although immature can be used to refer to any bird that isn't an adult. ::stage adult:: adult birds are sexually mature and are able to reproduce. adult birds will be in full adult plumage which may change depending on the season. Some birds have brighter plumage with clearer markings when in breeding season while in other birds, such as puffins, the shape and colour of their bills may change. | Egg tooth body part does a baby chick have that is used for getting out of the egg. | entailment | lookup |
::stage egg:: eggs are laid by female birds in clutches ranging in number from just 1 for condors to as many as 17 for the grey partridge. Eggs are incubated by one or both parents for a period of time until the embryo inside has developed into a chick which is ready to hatch. A chick may have to work for hours or even days to break through the shell of its egg. Most birds have a small bump near the tip of their beak called an egg tooth to help them hatch. ::stage hatchling:: a hatchling is a bird that has just hatched and may be almost completely naked apart from some fine down. Hatchlings eyes may not open and it is unlikely to be able to care for itself. The term hatchling is usually used to refer to altricial chicks which are undeveloped and unable to move around.

::stage egg:: eggs are laid by female birds in clutches ranging in number from just 1 for condors to as many as 17 for the grey partridge. Eggs are incubated by one or both parents for a period of time until the embryo inside has developed into a chick which is ready to hatch. A chick may have to work for hours or even days to break through the shell of its egg. Most birds have a small bump near the tip of their beak called an egg tooth to help them hatch. ::stage hatchling:: a hatchling is a bird that has just hatched and may be almost completely naked apart from some fine down. Hatchlings eyes may not open and it is unlikely to be able to care for itself. The term hatchling is usually used to refer to altricial chicks which are undeveloped and unable to move around. Hatchlings will stay in the nest for some time and will rely on their parents for feeding and to keep them warm. Precocial birds such as ducks and owls are relatively mature when they are born and are sometimes able to feed themselves and leave the nest soon after. ::stage nestling:: nestlings are chicks that are a few days old and are covered in soft down. There may be signs of flight feathers and nestlings eyes may have opened but they will be unable to leave the nest and will still rely on their parents for food and warmth. ::stage fledgling:: chicks that have developed flight feathers and wing muscles are known as fledglings. fledglings will have started to explore outside the nest but will still be under the care of their parents. Fledglings are fairly awkward and only able to fly for short distances but will be active and able to hop about. The length of time it takes for a chick to fledge varies between species. For example it takes 6 months before the chicks of the great frigatebird fledge and their parents feed them for a further 14 months. ::stage juvenile:: a juvenile bird is at the awkward teenage stage of being a bird. Juvenile birds will have left the nest and will be fully independent. juvenile bird will be in their first plumage and can look similar to adult birds although they may be duller with less defined markings. Out in the field it can be difficult to identify a juvenile bird and for most species of birds the length of time they are a juvenile is very short. ::stage subadult:: subadult birds are young birds that are older than juveniles but have still not developed adult plumage and are not sexually mature. Some birds such as house sparrows will become sexually mature at just a few months whereas larger birds such as golden eagles won't become sexually mature until they are 4 or 5 years old.

For example it takes 6 months before the chicks of the great frigatebird fledge and their parents feed them for a further 14 months. ::stage juvenile:: a juvenile bird is at the awkward teenage stage of being a bird. Juvenile birds will have left the nest and will be fully independent. juvenile bird will be in their first plumage and can look similar to adult birds although they may be duller with less defined markings. Out in the field it can be difficult to identify a juvenile bird and for most species of birds the length of time they are a juvenile is very short. ::stage subadult:: subadult birds are young birds that are older than juveniles but have still not developed adult plumage and are not sexually mature. Some birds such as house sparrows will become sexually mature at just a few months whereas larger birds such as golden eagles won't become sexually mature until they are 4 or 5 years old. The terms immature and subadult are interchangeable by many ornithologists although immature can be used to refer to any bird that isn't an adult. ::stage adult:: adult birds are sexually mature and are able to reproduce. adult birds will be in full adult plumage which may change depending on the season. Some birds have brighter plumage with clearer markings when in breeding season while in other birds, such as puffins, the shape and colour of their bills may change. | Juvenile birds do they call ducks and owls that are relatively mature when they hatch. | not_entailment | lookup |
::stage egg:: eggs are laid by female birds in clutches ranging in number from just 1 for condors to as many as 17 for the grey partridge. Eggs are incubated by one or both parents for a period of time until the embryo inside has developed into a chick which is ready to hatch. A chick may have to work for hours or even days to break through the shell of its egg. Most birds have a small bump near the tip of their beak called an egg tooth to help them hatch. ::stage hatchling:: a hatchling is a bird that has just hatched and may be almost completely naked apart from some fine down. Hatchlings eyes may not open and it is unlikely to be able to care for itself. The term hatchling is usually used to refer to altricial chicks which are undeveloped and unable to move around. Hatchlings will stay in the nest for some time and will rely on their parents for feeding and to keep them warm. Precocial birds such as ducks and owls are relatively mature when they are born and are sometimes able to feed themselves and leave the nest soon after. ::stage nestling:: nestlings are chicks that are a few days old and are covered in soft down. There may be signs of flight feathers and nestlings eyes may have opened but they will be unable to leave the nest and will still rely on their parents for food and warmth. ::stage fledgling:: chicks that have developed flight feathers and wing muscles are known as fledglings. fledglings will have started to explore outside the nest but will still be under the care of their parents.

::stage Egg:: The development of marine finfish eggs is temperature dependent among all teleost (bony fish). Once the egg is fertilized, the embryo will form inside the hardened egg. The embryo will start to develop organs, and eventually eyespots and the tail can be seen inside the egg. The embryo will develop pigmentation spots along the body. The tail will wrap around the egg to the head. If the species lives in warmer waters, the embryo will hatch more quickly. Colder water species hatch slowly, and the eyes and pigmentation will be fully developed at hatching. The tail of the embryo will break out of the shell and the embryo becomes a free-swimming larva. ::stage Larva:: Once the fish is hatched, it is known as a larva. Newly hatched larvae have a yolk sac that is a source of nutrition for the larvae. Larvae absorb their yolk sac for several days until they are developed enough to feed on live prey. Yolk sac larvae can survive for 2-4 days by feeding off their yolk sac food supply. This is called endogenous feeding. The length of the yolk sac period for larvae is dependent on the culture temperature and the species of fish. The warmer the water, the faster the fish will use up their yolk reserves. Once the larvae mouth has formed and the eyes are partially developed, the larvae can be offered a live feed. Feeding on organisms or particles in the water column is called exogenousfeeding. Live feed is essential to the early stages of developing larvae. Because their eyes are underdeveloped at hatch, the larvae need to be offered a feed that is moving around to help stimulate a feeding response. When the larvae hatch, they have a finfold around their whole body that looks like an outline when observed under a microscope. This finfold will eventually develop into fins, beginning with the process of metamorphosis. ::stage Juvenile:: Metamorphosis is the process that signifies the end of the larval stage. After metamorphosis, the fish are considered juveniles and will acquire characteristics of an adult fish: body features, coloration, fins, etc. Metamorphosis also denotes full organ development; it occurs at different times for different types of fish. For example, some fish will metamorphose in 20 days, whereas some will not go through the process until 4 months of age. Metamorphosis is a very stressful time for the fish, which means there is a point of high mortality, known as a bottleneck. The larvae are given a different type of feed during this period because they are now juvenile fish. Weaning fish to a new diet is also a stressful part of the culture process. Juveniles are usually resistant to stress (temperature, water quality, etc.) over time. As long as the culture environment remains healthy, the fish should thrive on dry feed and show significant growth rates. Juveniles are not considered adults until they become sexually mature. The developmental cycle is complete once spawning to egg and larvae to juvenile and adult has been accomplished. ::stage Adult:: Adults are characterized by their ability to reproduce. | Warm water species species of fish hatch more quickly. | entailment | lookup |
