Early Easter Eggs

posted in: Miscellaneous | 2

“One would think that the Easter Bunny has decided to come early this year, judging by the pale blue eggs that show up on my lawn. These are about the size of quail eggs and are laid directly on the grass, with no evidence whatsoever of any nest-building attempts. They are also unattended. I leave them undisturbed, and usually, after a day or two, rats, squirrels or other birds will break them and consume the contents.

“My wife assumed that since the eggs were blue, they could have been laid by kingfishers, which are common here. But we know that there is no relationship between the colour of the bird and the colour of its eggs. If there was, my pet lories and lorikeets would lay multicoloured eggs that would put most commercial Easter eggs to shame.

“I have ruled out the pigeons and doves that come frequently and that narrows the field of suspects to – the White Breasted Waterhen, the Common Myna and the Javan Myna.

“I believe that the last two are the most likely. Mynas of the genus Acridotheres (to which the above species belong) are known to lay bluish or greenish eggs.

“Those that I find in my garden are probably infertile. Some well-fed female birds do ovulate regularly, with or without males present – and the wild-bird feeding stations that I have set up supply food constantly. If eggs are infertile, female birds have been known to just drop them anywhere, and pay no further attention.

“That’s my assumption. Would anyone like to add more information to my observations?”

    Dear Chiu San,

    Are there any trees right above your lawn? What is the size of the egg? If not mistaken, munias also produced bluish eggs, so is the Little Heron that produced a bluish but larger egg. I think kingfisher lays white eggs, since they were hole nesters, they dont need to select a colour that is less obviously seen from far. The egg shell colors are also from a long adaptation process and did not just pick a random color usually. Thanks.

    Dear Jing Yi,

    There are no trees above that part of the lawn where the eggs are often found. They are about the size of domestic quail eggs, too big to be laid by munias. I used to see little herons in my old house, which was next to a canal, but have never seen any near the small, ornamental fish ponds at my present place.
