The Pigeons went on to lay two eggs of which the male and female took turns to incubate. However, after one fateful night, the female was found dead in another corner of my garden with its feathers all over the place, most probably thanks to the doings of a Siamese Cat seen wandering the street with an abnormally huge abdomen. One egg was broken on the ground while the other had a hole in it still in the nest (another predators’ doing?). The male was seen incubating in the nest still, oblivious to what had happened. But after one day reality sank in and he was seen chasing after another female.
It was survival of the fittest and the Bulbuls triumphed. The Yellow Vented Bulbuls’ nest was nicely camouflaged whereas the pigeons’ was pretty exposed and on low ground making it very vulnerable to predation. Losses due to predation mount up to two-thirds of all losses and most are found in open area (Oniki, 1979).
