Heermann’s Gulls form large breeding colonies on arid islands in the Gulf of California, Mexico, from March through July. The largest colony exists on Isla Raza, where an estimated 90–95% of the total world population breeds 1. This photo by Basar from Wikipedia Commons shows the adult in breeding plumage.

It has been a few years since I could share some good news about the Pied Oystercatchers breeding along the coast near Broome. Hopefully you won’t mind me writing a bit more this year about Pied Oystercatchers during the breeding season! The two eggs normally hatch at least a day apart and sometimes longer.

After 28 days of sharing the duty of sitting on three eggs we finally had the arrival of our first Pied Oystercatcher chicks for 2012 on Friday August 3rd. It is unusual for three eggs to be laid here in Broome and many eggs do not even hatch due to predation each season.

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”.

However, the lockdown forces me to go deeper and deeper into my photo collection, if I want to write anything at all. Contrary to alleged preferences among humans, the golden-headed cisticola has a shorter tail during the breeding season ( source ). It breeds in tree holes, presumably explaining the more commonly used name for it.

She also monitors Pied Oystercatchers breeding along a 23km stretch of beach by bicycle and on foot. Speaking of pregnant snakes, do sea snakes lay their eggs ashore like sea turtles or do they keep them internally until the young are ready to hatch/ be born, like some sharks?

The Achiever’s survey voyages took place from 2005 to 2008; the goal was to collect baseline data on sea mammals and marine birds. The species was seemingly killed off by feather hunters, but then, after years, reappeared at the site of one of the deserted breeding colonies, Torishima Island in Japan.

A breeding bird atlas is a special kind of book. For the nature lovers and birders who participate in breeding bird surveys, the atlas represents hours, often hundreds of hours, of volunteer time spent within a community of citizen scientists doing what they love, observing birds. So, what exactly does a breeding bird atlas contain?

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. …because cooperative breeding facilitates defense against brood parasites.

Each male builds numerous nests, most of which are rejected by the female, who will eventually select a nest she is happy with, allow the proud architect who usually hangs under his masterpiece to mate with her and then begins the breeding process.

Mechanisation (ploughing and harvesting in particular), chemical fertilisers and pesticides, fire and predation all contribute to high mortality of eggs, chicks, juveniles and incubating females. In the last year, a broken bustard eggshell was found, but since no displaying was observed, those could have been unfertilized eggs.
