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

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.

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.

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.
