We have often suspected that the Sand Goannas would steal eggs as a food source from the Pied Oystercatcher nests if they found them. The two pairs should have been close to hatching their eggs from their first clutch. The pair of Pied Oystercatchers to the north have now laid a second clutch of two more eggs.

A paper on the species asks the important question “Does nest sanitation elicit egg rejection in an open-cup nesting cuckoo host rejecter?” ” To rephrase: if you put some trash into a nest of a bird along with a cuckoo egg, does that improve the chance that the cuckoo egg will be kicked out? How to find out?

Well, not quite like clockwork, because this year one pair of Pied Oystercatchers on Cable Beach laid their first clutch of eggs a bit earlier than normal.

The Cuckoo Cuculus canorus has a bad reputation because of its habit of laying its eggs on the nests of other birds, who then raise their young. They then settle in their newly acquired home, lay their eggs and raise their brood. The swifts arrive, seek the swallows out, find their nests and evict the tenants!

In California, coveys break up and pairs begin forming in February or March, followed by nest building and egg laying in May or June. She will usually lay 12 to 17 eggs, averaging five per week 1 , before beginning incubation. Occasionally, larger clutches occur due to egg dumping by other females. References: 1 Baicich, Paul J.

Generally the more exposed the egg are, the more hidden or camouflaged the nest should be. Giant Hummingbirds build cup-shaped nests where eggs are exposed, but rather than hiding or camouflaging the nest, the biggest of all hummers generally places its nest in cacti. Nest predation is the driving force of nest site selection by bird.
