I was soooo excited about getting to know the Middle East, as well as some of its exotic species. The Streak-backed Oriole shown at the head of this post is far from an uncommon species in Paso Ancho. This female Rose-throated Becard also gave me my best photo so far of its species.

Welcome to Invasive Species Week!

10,000 Birds

Here at 10,000 Birds we are going to dedicate the coming week, from today until Saturday, to invasive species. We plan to use the broadest possible definition of invasive species, including species that are expanding under their own power and even species that are not, to the best of our knowledge, causing harm to species native in the range into which the invaders are expanding. But why are we covering invasive species at all? Will native species suffer?

Furthermore, another redpoll species found in Europe—the Lesser Redpoll—also had extremely similar DNA sequences. In nature, one of the key differentiators among distinct species is assortative mating , that is, members of a group breeding with each other more often than they breed with members of another group.

Invasive Species Week Wrap-Up

10,000 Birds

Perhaps our outrage at invasive species can be a bit hypocritical at times. Listers are quick to put aside their condemnation of invasive species once they attain that coveted status of exotic: not native, not fully naturalized, but established well enough to be countable by the prevailing authority. The rapid proliferation of the European Starling is, on the species level, equivalent to incalculable fortunes of billionaire moguls.

Africa’s endangered species

10,000 Birds

More than 150 bird species are known to have become extinct over the past 500 years, and many more are estimated to have been driven to extinction before they became known to science. The bulk of the recent bird extinctions has been on islands, where species are more susceptible to extermination due to smaller ranges, lower population sizes and a lack of adaptation for coping with introduced predators.

Six Months Birding in Costa Rica, 620 Species of Birds

Although Bobolinks are a very rare migrant, lots of other birds are possible, more than enough to rack up hundreds of species over the course of the year. Each January, I hope to identify at least 600 species over the next 12 months, this year, I’m hoping that Marilen and I (aka Team Tyto ) will find 700.

10,000 Birds

As for introduced or reintroduced species it would only count if it was third generation reintroduced. One preoccupation I have already alluded to in listing is whether introduced species count. Quite aside from how many introduced exotic species we have here (hint, it’s a lot), any number of the native species you might see could qualify as “introduced” by some measure or another.

Unique Sea Horse Species Threatened

Critter News

A species of seahorse unique to the waters of the Gulf Coast could face extinction because of the Gulf of Mexico oil spill, warns marine conservation organization Project Seahorse. Without careful intervention, the dwarf seahorse (Hippocampus zosterae) could virtually disappear within a few years, while many other fish populations, including several other species of seahorse, face a similarly bleak future as cleanup continues. “We’re

U.S. Endangered Species Act: The System Works

A prime example is a report newly released by the Center for Biological Diversity which suggests that, by and large, in the United States, the Endangered Species Act is indeed helping to save the birds it protects. Interestingly, researchers found that birds protected as endangered species were better off than unprotected birds—with overall declines of 24% since 1974—because of intensive and active management.

Endangered Species Act: Potential Downlisting for Hawaiian Goose (nene)

More than 50 years ago, the Hawaiian Goose (Nene) was one of the first birds listed under the Endangered Species Act, part of the inaugural “ Class of 1967 ”. Under the Endangered Species Act, any listing, uplisting, downlisting, or removal from a list requires a formal “rulemaking” process. It provided a summary of the basis for downlisting and analyzed the criteria used to determine whether a species ought to be downlisted.

Grallards: New Zealand’s Next Extinction or Newest Species?

10,000 Birds

The obvious choice was the Mallard , that plucky familiar northern hemisphere species that is the father of the even more familiar domesticated duck. In fact, as the species was quickly identified as as creating hybrids with Grey Ducks, the opinion was by the 1920s that the species shouldn’t be released further. His largess in providing birds for release (and ability to get official sanction for this) lead to a much more aggressive attempt to establish the species.

Christian Science Monitor Calls for Endangered Species Hour

Critter News

I like this opinion piece from the Christian Science Monitor which calls for an "Endangered Species Hour." The Christian Science Monitor rightly points out that citizens and consumers need to get involved in endangered species protection, because at the CITES level, it's all about money and international politics. But jobs that depend on harvesting endangered species will quickly disappear if those species are not protected. "Earth Hour" was held yesterday.

How to Help Cerulean Warblers, Other Migrant Species, and Resident Birds in Costa Rica

A wonderful variety of bird species are waiting to be seen and among them are many a birder’s favorite avian group, the wood-warblers. Among the most desired bird species during May migration, brightly colored, beautiful and boldly patterned, how can a birder not get hooked on spring warblers? Threatened by loss of habitat both on breeding as well as wintering grounds, a few species have even become endangered or at least on a perilous track towards that worrisome designation.

How Many Bird Species on Poas Volcano, Costa Rica?

Recently, while guiding on the slopes of Poas, without too much effort, we had more than a hundred species. Such a birdy day and yet, one that still lacked quite a few species. Since I have spent a fair number of days on most sides and accessible areas of the volcano, I have a fair idea of what lives there but before making the list, I had to delineate the area used for the species tally. Purple-throated Mountain-gem is another of several common hummingbird species on Poas.

I should also note that the abstract for the Condor paper proposes five , not four, species.

Animal Ethics

The rights view is not opposed to efforts to save endangered species. But though the rights view must look with favor on any attempt to protect the rights of any animal, and so supports efforts to protect the members of endangered species, these very efforts, aimed specifically at protecting the members of species that are endangered, can foster a mentality that is antagonistic to the implications of the rights view.

The man who saved species

Both species had undergone massive declines since the arrival of humans and where in a perilous position in the 1970s.
