It didn’t occur to me till I started reading The Falcon Thief: A True Tale of Adventure, Treachery, and the Hunt for the Perfect Bird that there was also a possible threat to the eagle herself: poachers, who steal raptor eggs and chicks. McWilliam realizes he’s dealing someone special, a career falcon egg-thief.
In addition to their homing tendency, breeding swallows are attracted to old nests. It is illegal for any person to take, possess, transport, sell, or purchase them or their parts, such as feathers, nests, or eggs, without a permit. Completed nests during this breeding season cannot be touched without a permit from the U.S.
In my imagination, the job of a male Australian Brush Turkey is pretty similar – removing or adding bits and pieces to his pile of rotting vegetation in order to get the right temperature to incubate the eggs buried underneath to hatch. It breeds in tree holes, presumably explaining the more commonly used name for it.
While females hatch from larger eggs and are initially heavier than their brothers, after ten days, the male chicks weigh almost 50% more than their sisters, as they receive a higher quantity and quality of prey from their parents ( source ). .” ” ( source ).
Image by Adam Riley Of the 115 African species now listed as Endangered or Critically Endangered, nearly half occur on the islands surrounding Africa or are non-breeding migrants to Africa. In this blogpost I will discuss ten of the 60 endangered species that are resident on the African continent.
” The website www.jwcpheasants.com seems to endorse polygamy for this species despite this being illegal in the USA for other animals such as humans. The site states that in captivity, “two hens can be paired with one male.” I lowered the volume and after a while they got used to it and slowly went back to sleep.”
A study on the breeding biology of Whitehead’s Broadbill was just published in May 2023 but leaves a bit of a puzzle as the breeding success is described as relatively high, meaning there should be other reasons for the population decline of the species. Leave the bad jokes to me, please.
One paper describes them breeding in a human settlement in abandoned clay jars. ” While this species is not explicitly associated with infanticide, the fact that the bird lays 1-3 eggs but only ever raises one chick also implies that the species should also be closely watched by child protection agencies.
The Bar-backed Partridge was also one of four focal species in an investigation into illegal bird hunting in Southwestern China. Another, somewhat more interesting study suggests that nest sanitation (ornithologists speak for cleaning up your room) helps Common Tailorbirds to recognize and eject parasitic eggs.
When these birds breed, this can lead to highly cringeworthy announcements, for example from Adelaide Zoo : “We have egg-citing news!” Breeding pairs form exclusive social bonds, yet each partner will still mate with other individuals.” It seems that quite a few zoos keep Tawny Frogmouths. ” ( source ).
Hopefully, the winter time in Shanghai gives the Black-faced Buntings some time to relax from the challenges of the breeding season. Fortunately for the buntings, they seem to detect most cuckoo eggs smuggled in (75% in one study). Maybe there is some justice in this world after all. Better safe than sorry.
