As a birder, I’ve found this place to be a complete treasure trove for many species difficult to see elsewhere. Personally I’ve seen over a hundred species over several birding trips there, the overall species list for the location is approximately 160 – a tally that will only increase.

Well, you could look up other North American swallows on eBird, for comparison. Assuming that several of the observers involved had made multiple observations, that probably represents only around one hundred people having ever reported this species, even though it breeds in a country bordering the United States. Could the be?

Just last year, 5 new bird species and 5 new subspecies were discovered in a few short weeks of fieldwork on the islands of Taliabu, Peleng and Batudaka. In recent years Indonesia has been competing with the Andes as the region giving rise to the biggest number of undescribed bird species (naturally, all of them endemics).

Wood Sandpipers- Tringa glareola are a shorebird species that are found on inland fresh water rather than along the coast. Wood Sandpipers can be very aggressive to others of the same species and it is not unusual to see a pair face off at each other and then fly up at each other to defend a feeding area.

Finally in 1799, the first visitors on this volcanic land were a group of French seal hunters who were after the fur seals that can be found hauled out on the beaches for fur and oil, which almost wiped out the local population of the species. About half of all breeding Wandering Albatross nest on the Prince Edward Islands.

Since then their range has spread across the United States and southern Canada, and they remain a sought-after game species. While the females are much drabber by comparison, their gold/tan color and black spotting makes them stand out from other species as well. During some seasons, millions of male pheasants are killed.

Major extinction events that are geologically instantaneous have been followed by periods of time with reduction of species or unstable habitats that last for hundreds of thousands or millions of years. There are about 10,000 species of them, after all, which is a lot for a vertebrate. But, that is also a naive view.

For example, years ago, Eiton Tchenrov postulated that the wild progenitor of the domestic dog, some subspecies or another of wolf, could benefit from overlapping its breeding territory with human hunters. This often applies in animal behavior and ecology, and this often comes about in relation to predator pressure.

There is indeed little good that can be ascribed in retrospective to this period, and the little good there is pales in comparison to the bad things.

A quite uncommon bird – there are only about 6000 pairs on the planet and this is one of only a handful of my observations of this species. Two-thirds of the world’s population breeds colonially on Greek islands. My first one was about 20 years ago not far from Thessaloniki, three dark morph birds, and I still remember it.

Third, observing and photographing breeding birds and their young have become acts of ethical confusion as birders, photographers, and organizational representatives debate the impact of our human presence on the nesting process.

The maximum population size may be closer to 20 billion in the fall, and 10 billion at the start of the Spring breeding season. If, however you pick the 10,000 number, they will be randomly distributed among the lest common 10 species.
