By the size of the juvenile birds the adults must have laid the eggs several months ago when the rains came to that area of Western Australia. Discovering this breeding colony of Yellow-billed Spoonbills was definitely the highlight of our walk. As you can imagine I soon got busy taking photographs of the Yellow-billed Spoonbills.

It didn’t occur to me till I started reading The Falcon Thief: A True Tale of Adventure, Treachery, and the Hunt for the Perfect Bird that there was also a possible threat to the eagle herself: poachers, who steal raptor eggs and chicks. McWilliam realizes he’s dealing someone special, a career falcon egg-thief.

If the male’s color fades after the first egg, the female reacts by laying a smaller second egg – seemingly deciding that it is better to cut her losses as the male apparently is the avian equivalent of a deadbeat father. But if you already drive a Porsche, this should not really bother you.

In fact we often don’t have any chicks within two weeks of the eggs hatching and other pairs along the coast have not been successful yet this season. More eggs have been laid and hopefully other pairs of Pied Oystercatchers will soon have young to care for. Female on the left and two chicks next to the male Pied Oystercatcher.

There is egg predation, chick loss and sometimes possibly just some “bad parenting”!

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.
