Reverse migration, also called reverse misorientation, [1] is a phenomenon whereby a bird migrates in the opposite direction to that typical of its species during the spring or autumn. [ 1 ] For example, if a bird breeding in central Asia reverses its normal southeasterly migration, as shown by the orange arrow, it will end up in Western Europe ...
Her brother, Howard, later commented that if she would paint the images for such a book he would collect them for her. [2] In 1876, Jones viewed James Audubon's The Birds of America at the World's Fair in Philadelphia and was inspired to undertake the project. [5] The initial instalment of the book was extremely well received.
Oology (/ oʊ ˈ ɒ l ə dʒ i /; [1] also oölogy) is a branch of ornithology studying bird eggs, nests and breeding behaviour. The word is derived from the Greek oion, meaning egg. Oology can also refer to the hobby of collecting wild birds' eggs, sometimes called egg collecting, birdnesting or egging, which is now illegal in many ...
The mousebirds are birds in the order Coliiformes.They are the sister group to the clade Cavitaves, which includes the Leptosomiformes (the cuckoo roller), Trogoniformes (), Bucerotiformes (hornbills and hoopoes), Piciformes (woodpeckers, toucans, and barbets) and Coraciformes (kingfishers, bee-eaters, rollers, motmots, and todies).

A young bird on its first migration flies in the correct direction according to the Earth's magnetic field, but does not know how far the journey will be. It does this through a radical pair mechanism whereby chemical reactions in special photo pigments sensitive to short wavelengths are affected by the field.
Deep cup nest of the great reed-warbler. A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too ...
The birds in this genus are infamous for laying their eggs in other birds' nests. The female cowbird notes when a potential host bird lays its eggs, and when the nest is left momentarily unattended, the cowbird lays its own egg in it. The female cowbird may continue to observe this nest after laying eggs.
The nests vary in size, shape, material used, and construction techniques from species to species. Materials used for building nests include fine leaf fibers, grass, and twigs. Many species weave very fine nests using thin strands of leaf fiber, though some, like the buffalo-weavers, form massive untidy stick nests in their colonies, which may ...
