If you have always wondered what the minimum anesthetic concentration for isoflurane and sevoflurane for the Crested Serpent-eagle is, science has an answer. The breeding ecology of the Yellow-bellied Warbler was actually studied exactly here at Nonggang in 2019 by 3 Chinese researchers. So you just have to look at the photos for once.

According to the HBW, when breeding, male birds do most of the incubation and parenting while females often leave the nest up to one week before the eggs hatch. According to Couzens, after laying the eggs, females sometimes immediately abandon their first mate and pair up with another male. How efficient. How surprising.

Scientists were largely limited to studies birds in breeding colonies, at least those we knew about and that were accessible (and, if you think that’s a complete list, you haven’t read the news that came out this week about a new colony of Adélie penguins found in the Danger Islands, Antarctica). Technology to the rescue!

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.

They breed in colonies scattered around the Antarctic continent (the number ranges from 60 to 70, and as Kooyman points out, the colonies can drastically change in size from year to year) on the ice (and one of the things I learned from this book is how many different kinds of ice there is in the Antarctic) in the darkest months of winter.

However, it’s not until the end of the first week of May that the majority of the breeding birds return to our village. The first eggs are usually laid at the end of May or sometimes in the first week of June, but this can vary depending on the weather. Both sexes incubate, with the eggs taking an average of 19 or 20 days to hatch.

The fields near the Tiaozini mudflats look very much like a lunar landscape, but this does not seem to keep a number of species from breeding there, sometimes directly on dirt roads. But now back to birds … Little Ringed Plovers also seem to like to breed directly on the road. Blandness sells.

However, it is kind of sophisticated in that the females lay very individualized eggs in order to be able to detect the added eggs of parasite cuckoo finches. Let’s hope it can find some relatively unfragmented habitat for breeding – studies show that the failure rate of nests is much higher in fragmented habitats.

This bit of science is a nice final counterpoint to an account that has emphasized art, history, and literature.

Earlier attempts to spread the risk around had failed, so Don and his team applied science to the problem, spending several months studying the birds in the wild in order to work out how to care for them and to decide what type of habitat to release them into. It worked, and the translocated birds were soon breeding.

Unfortunately, the Ashy Drongos did not exactly do what he predicted that they would do – mob potential predators more frequently during the breeding season and mob the more dangerous predator (in this case, the Black Eagle) more intensely. If you do not want to be put in a cage, it presumably helps to be a bit aggressive.

Hopefully, the winter time in Shanghai gives the Black-faced Buntings some time to relax from the challenges of the breeding season.

I have written about the interesting sex life of these jacanas a few times already (short version: female mates with male, lays a bunch of eggs for him to incubate and raise the chicks, leaves him, finds another male, repeat). Apparently, after a male first mates with a female, he throws out the first one or two eggs she lays in their nest.
