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.

You can see some of my older Lassen Park posts featuring several other species from this beautiful park here. This week I am reporting on the Cassin’s Finch ( Haemorhous cassinii ), another western species found nesting in Lassen Volcanic National Park. This is the male of the species (click on photos for full sized images).

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.

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.

Most breed in the Chatham Islands or in the islands to the south of South Island, but a few breed on the Three Kings Islands at the tip of North Island as well. As albies go they seem to be doing better than most species, and are only listed as Near Threatened by the IUCN. For size comparison, a scrum of albies.

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.

When the land is flooded after rain it will move inland and breed at the ephemeral lakes and raise its young there. It is a very easy species to find in the Broome area and present throughout the year. The closest similar species is the Banded Stilt , but it is a stockier bird with shorter legs.

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.

Horned Larks breed widely over North America, including up here in the High Arctic. Here they are a common breeding bird, one of our two species that migrate from here to Europe and then south. At the same time (and sometime the same location) we have Semipalmated Plovers breeding, which makes identification a challenge.

Predators that rely on lemmings, like the Snowy Owl , took advantage of the bounty and had great breeding success, raising large broods which, after the lemming population crashes, dispersed far and wide.
