Interspecific egg-dumping by a violet-green Swallow in an active Western Bluebird nest.

Observations of birds laying eggs in nests of other species are of interest because this behavior, when timed appropriately and directed at nests where parents fail to recognize foreign eggs and offspring, may be the starting point for evolution of interspecific brood parasitism.

Rumah Walet Balikpapan Miliki Potensi


kapet.org
BALIKPAPAN ternyata bukan hanya dikenal memiliki potensi sebagai kota transit, tetapi juga memiliki potensi bisnis rumah walet yang cukup besar. Namun sayangnya, hingga kini potensi agribisnis ini belum tergarap maksimal karena dipandang sebagai bisnis yang mengandalkan hoki. Menurut pengamat walet Ir Herman, 90 persen penghasil sarang burung dengan liur ini berjenis walet (collocalia fuciphaga) bukan seriti seperti di Pulau Jawa. “Berdasarkan pengamatan saya beberapa tahun terakhir, jenis walet lebih mendominasi yakni sekitar 90 persen. Tidak seperti di Pulau Jawa hanya 40 persen, sementara 60 persen lagi adalah seriti,” ungkapnya.

Birds in Chernobyl choose to nest in sites with lower levels of background radioactivity, researchers discover, but how they can tell remains a mystery.

Anders Møller at Pierre and Marie Curie University in Paris, France, and Tim Mousseau at the University of South Carolina in Columbia, US, erected more than 200 nest boxes in the Red Forest, about 3 kilometres away from the nuclear reactor that exploded in 1986.

Hirundo


en.wikipedia.org
From Wikipedia, the free encyclopedia
The bird genus Hirundo is a group of passerines in the family Hirundinidae (swallows and martins). These are the typical swallows, including the widespread Barn Swallow. Many of this group have blue backs, red on the face and sometimes the rump or nape, and whitish or rufous underparts.
All of the species are found in the Old World, although one, the Barn Swallow, is cosmopolitan, also occurring in the Americas.
Genetic evidence has recently shown that many of the species previously included in Hirundo are less closely related than their appearance might suggest; these species are now treated in the separate genera Cecropis (e.g. Red-rumped Swallow Cecropis daurica, previously Hirundo daurica) and Petrochelidon (e.g. Cliff Swallow Petrochelidon pyrrhonota, previously Hirundo pyrrhonota); they are as distinct from typical Hirundo as the House Martins in the genus Delichon.

Authentic bird's nest soup is made using the nests of the swiftlet …


personal.umich.edu

Authentic bird’s nest soup is made using the nests of the swiftlet, a tiny bird found throughout southeast Asia. The swiftlet lives in dark caves, using a method of echolocation similar to the bat to get around. Instead of twigs and straw, the swiftlet makes its nest from strands of its own gummy saliva, which hardens when exposed to air. Humans who harvest the swiftlet nests often come from families that have made their living this way for generations. Prying the nests from the cave walls is extremely dangerous, and many harvesters die each year.

Birds' nests cause delay in bridge construction


Rhinelander Daily News, WI – 3 hours ago
TIGERTON, Wis. – A handful of swallow nests might hold up construction work on a Shawano County bridge indefinitely.

Work on the Tigerton bridge was scheduled to begin Monday. But on Friday the contractor found a number of nests on the structure’s underside, causing a delay until state officials could decide how to work around the federally protected nests.
