Some female zebra finches foist a part of their eggs on their neighbors.
In 2007, researchers of the Max Planck Institute for Ornithology found a gene related to individual variation in exploratory behavior in great tits.
Reptiles are not known to be the most social of creatures. But when it comes to laying eggs, female reptiles can be remarkably communal, often laying their eggs in the nests of other females. New research in the September issue of The Quarterly Review of Biology suggests that this curiously out-of-character behavior is far more common in reptiles than was previously thought.
Why do some species of birds lay only one egg in their nest, while others lay 10 or more?
It's not always easy spotting the cuckoo in the nest. But if you don't, you pay a high price raising someone else's chick. How hosts distinguish impostor eggs from their own has long puzzled scientists.
By Jeremy Manier and Tim De Chant, Chicago Tribune Jun. 27--When a falcon swoops from the sky to seize its fleeing prey, no one would mistake the sleek predator for a gaudy parrot.
Male seagulls may be more vulnerable to their environment during embryonic development than females, according to Maria Bogdanova and Ruedi Nager from the University of Glasgow in the UK. Until now, the sex differences in developmental rate and susceptibility to unfavorable conditions during the embryonic stage in birds have received little attention. The paper has just been published in Springerâ€™s journal, Behavioral Ecology and Sociobiology.
Competing against older brothers and sisters can be tough work, as any youngest child will tell you. But new research from a biologist at the University of North Carolina at Chapel Hill shows that when it comes to some birds, you should reserve any underdog sympathies for the first born â€“ or rather, first laid â€“ siblings as well.
Birds' eggs are unique in their diverse pigmentation. This diversity is greatest amongst perching birds (order Passeriformes: 60% of all bird species), which include many familiar species including tits and warblers. Despite intense interest, the purpose, in most species, of these patterns was unknown.
Ornithology, a branch of zoology, is the study of birds. The term ornithology is derived from the ancient Greek words for bird and rationale or explanation. This study differs from other sciences because amateurs often take part in studies and because birds are commonly seen. It is thought that ornithology developed in the same manner than biology developed. Drawings from the Stone Age show the earliest interest in birds and the remains of over eighty bird species have been found at excavated...
