In the popular imagination, Hawaii is a tropical paradise. (No, With climate change appearing to expand the skeeters’ range, according to recent research in Science Advances , the birds have fewer safe places to hide. And if you’re lucky enough to be on the island of Hawaii next weekend (Sept. Take birds.
Now that Hawaii is in the ABA Area , the next additions should be Puerto Rico and the U.S. The Hawaii vote made it clear that that the ABA Area is about political borders, not geographical or ecological ones, and the two Caribbean territories have long been part of the United States. But even with Hawaii, there are many U.S.
Aplomado Falcon ( Falco femoralis ) by Jon David Nelson Shakeups for shearwaters and murrelets Xantus’s Murrelet ( Synthliboramphus hypoleucus ) has been split into California-breeding Scripps’s Murrelet ( Synthliboramphus scrippsi ) and Baja-breeding Guadalupe Murrelet ( Synthliboramphus hypoleucus ).
For example, Danny Bystrak (Breeding Bird Survey) and Dave Ziolkowski (Bird Banding Lab) of the USGS indicated that changes would not have a substantial negative impact on their programs, and would be just a “minor annoyance.” Was there confusion that impacted data collection or research or birding? Did the process work?)
Specifically, the notice summarizes the long history of Hawaiian Goose conservation, including written recovery plans in 1983 and 2004 , implementation of those plans, and research, including a population viability analysis. Also, research filled in many knowledge gaps and informed conservation efforts.
Irruptions of Snowy Owls in 2011 and again in 2013 found these Arctic birds wintering well south of their usual range , in some cases straying down to Bermuda and even Hawaii. (I But new research, published in The Auk , suggests that this narrative may not provide the whole story.
So, while waiting for evolution to produce new birds for our life lists is inadvisable, we sometimes catch a break and every few years get a new species or two when some genetic research or study of breeding distribution presents enough evidence to split what was once considered a single species into a few new ones.
Well-researched and footnoted, these sections never feel disconnected from the more personal sections. I ended up looking for photographs of Peregrine hack sites, captive breeding aviaries, Hawaii tropical forest, and the California Condors of the Grand Canyon on the Internet. Endangered. Extinction. Conservation.
27, 2015 Christian Gutierrez, Raymond Justice, and Carter Mesker went on a camping trip to Ka’ena Point Natural Area Reserve on Oahu, Hawaii. Ka’ena Point is also a breeding ground for the Federally protected Laysan albatross, where 45 nests were being carefully monitored by the non-profit Pacific Rim Conservation.
A bit surprisingly (at least to me), the Kalij Pheasant has been introduced and established as a gamebird in Hawaii. This turned out to be nice for one researcher who thus could do the research for her Ph.D. Interestingly, in her work, the researcher found that the birds live in small groups dominated by a single male.
The rest of Mexico is not included, nor is Hawaii (which isn’t in North America, after all, but has been accepted as part of the American Birding Association area). I am particularly happy to see that the bird communication section includes recent research on singing female birds. These are all informative and current.
Several years ago, I read about the enormous colonies of breeding birds in the Northwestern Hawaiian Islands and I did some research to satisfy my curiosity. ( Google Scholar is an excellent resource and free full-text PDFs can be located for many papers, particularly when research is taxpayer-funded.
The guide covers over 650 species, most of the breeding birds in the United States (minus Hawaii) and Canada (like most guides with ‘North America’ in its title, it does not include Mexico or the Caribbean). Acorn Woodpeckers use both communal and cooperative breeding strategies which vary widely among family groups.
