In the slightly frighteningly named journal “Science of The Total Environment”, there is a paper on organochlorine compounds in Purple Heron eggs nesting in sites located around a chloralkali plant (Ebro River). Summary result: relevant chemicals emitted by the plant can be found in the eggs. Bye, bye, Lesser Coucal.

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. But maybe that is actually a good thing.

In Europe, most of them winter south of the Sahara but an increasing share winters north of it – which sounds like an interesting research topic for people who, ahem, find such topics interesting. It is rumored that one of the researchers later became a software developer. No need to remind us all the time.

The Large-billed Crow ( video ) is one of the natural enemies – in the study above, it predated 19 eggs from four pitta nests. The Lesser Coucal has a characteristic vocalization that can be heard in this video (along with the usual China-typical background noise – China is not a quiet place in general).

Shanghai parks are rather crowded and noisy places, but the goshawks – who unlike me have lived in China all their lives – apparently do not mind. Apparently, after a male first mates with a female, he throws out the first one or two eggs she lays in their nest. but they do.
