Among birds the Egyptian Vulture uses rocks to crack Ostrich eggs, the New Caledonian Crow and Woodpecker Finch (one of several Darwin Finches of the Galapagos Islands), uses sticks to extract grubs from inside a branch. This is similar to the fact that all birds, even first time breeders within a species build identical nests.

I should have known that birding High Island meant I would be 20 minutes away from a place where hundreds of thousands of shorebirds and waterbirds rest, feed, breed, and generally have a good time. I love American Avocets and I rarely see them in such marvelous breeding plumage, so I was in heaven. Clapper Rail. Back to the Flats.

The breeding ecology of the Yellow-bellied Warbler was actually studied exactly here at Nonggang in 2019 by 3 Chinese researchers. Some Thai researchers looked at the breeding ecology of the Buff-breasted Babbler and published their findings in the somewhat unsuitable-sounding journal “Agriculture and Natural Resources”.

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. This is a very bad photo of a Fruithunter. Still, a bad photo.

The vast majority of the 10,000+ living species of birds are passerines, and the vast majority of those have a similar system of breeding: Mom and dad bird make a nest and share parental responsibilities roughly equally, if not identically. In the latter, three or more adult individuals contribute to the raising of offspring.

Of course, it is hard to resist looking at a paper titled “Host personality predicts cuckoo egg rejection in Daurian redstarts” Basically, the personality of a female redstart (bold or shy) predicts the responses to parasitic eggs – bold hosts are more likely to reject parasitic eggs.
