Studies on improving ostrich egg hatchability. Also, I learned that in the US , ostrich eggs are priced at $40-$75. Ostriches originated in Asia.

We have been busy walking the beach and keeping an eye on our local Pied Oystercatchers and the two pairs that laid their eggs earliest for the 2018 breeding season and successfully hatched out their chicks have now lost their chicks to predation. They have only laid one egg so far and another may be laid within a day.

This is our thirteenth year of observing Pied Oystercatchers breed along the coast near Broome and it gets easier every year! They always nest from the end of June and they always nest in the same place or within a few metres if there is disturbance around the breeding territory. They are so predictable!

The nickel was placed in the nest for the photo to show me the size of the egg for identification purposes, then removed. Even though the female lays only two eggs per nest attempt, they enjoy a protracted breeding season in which multiple nesting attempts can occur every 30 days, and in Southern locations, nearly year round.

“Do you see the eagle?” The Osprey is one of the true cosmopolitans of the avian world, found on six continents and breeding on five. Time enough, I suppose, for our newcomers to figure out that those aren’t eagles. “Look,” one said to the other. Missoula knows Ospreys and embraces them.

As the national bird of Namibia, Zambia, and Zimbabwe, the African Fish Eagle is usually very busy whenever it stays in these countries, giving speeches, opening shopping centers, etc. However, it is kind of sophisticated in that the females lay very individualized eggs in order to be able to detect the added eggs of parasite cuckoo finches.

I love American Avocets and I rarely see them in such marvelous breeding plumage, so I was in heaven. Clapper Rail. Back to the Flats.

In the non-breeding season, male Baya Weavers sometimes enter the basket-making trade, often with considerable success. Meanwhile, the females seem to have a much more relaxing life, at least in this early stage of the breeding season. You can see why here. It very effectively forms a small foraging group in this manner.

The tiercels (young Peregrines) must deal with Golden Eagles, Ravens, adult Peregrines, and foxes; they must also learn to navigate the skies and make their own kills, luckily these skills appear to be innately learned. It’s not easy. Well-researched and footnoted, these sections never feel disconnected from the more personal sections.

Unfortunately, the Ashy Drongos did not exactly do what he predicted that they would do – mob potential predators more frequently during the breeding season and mob the more dangerous predator (in this case, the Black Eagle) more intensely. If you do not want to be put in a cage, it presumably helps to be a bit aggressive.
