Swallow adult feeding begging young in the nest. Parental care is a behavioural and evolutionary strategy adopted by some animals, involving a parental investment being made to the evolutionary fitness of offspring. Patterns of parental care are widespread and highly diverse across the animal kingdom. [1]
The most common maternal behavior among frogs is egg attendance, wherein the mother will remain near her eggs as they develop to protect them from predators. [9] A mother may also stay with her clutch in order to prevent desiccation, as she can rehydrate them by positioning themselves above the eggs, a behavior known as ventral brooding. [10]
Altricial young are born helpless and require care for a length of time. Altricial birds include hawks, herons, woodpeckers, owls, cuckoos and most passerines. Among mammals, marsupials and most rodents are altricial. Domestic cats, dogs, and primates, such as humans, are some of the best-known altricial organisms. [14]
Some animals starve to death shortly after birthing their young while others are eaten by their own young -- but these mothers make the ultimate sacrifice. Click through for 10 animal mothers that ...
The provision of care, by either males or females, is presumed to increase growth rates, quality, and/or survival of young, and hence ultimately increase the inclusive fitness of parents. [ 2 ] [ 3 ] [ 4 ] In a variety of vertebrate species (e.g., about 80% of birds [ 5 ] and about 6% of mammals), [ 6 ] both males and females invest heavily in ...
Once they leave the den and can chew, the parents and pups from previous years regurgitate food for them. Wolf pups become independent by 5 to 8 months, although they often stay with their parents for years. In contrast, dog pups are cared for by the mother and rely on her for milk and protection but she gets no help from the father nor other dogs.
While we wish our dogs could never grow up, especially when we have one of the 50 cutest dog breeds as puppies, the next best thing is a dog that says small throughout their entire life. If you ...
The word is most often used for the offspring of mammals, but can be used for any animal that gives birth to multiple young. In comparison, a group of eggs and the offspring that hatch from them are frequently called a clutch, while young birds are often called a brood. Animals from the same litter are referred to as littermates.
