In light of spring’s recent arrival, do you ever find yourself wondering how some species are able to withstand freezing, wintery days and yet still thrive in summer’s heat? My research proposal “ Towards a mechanistic understanding of feather colors ”, investigates the genetic basis for color patterns in birds. Maria’s Project.
” But here I’m using it because someone ELSE used it … the Bird 10K project is an effort to do the whole DNA thing they do on groups of species on the whole mess of 10K (or more) birds. Beagle had an enormous impact on Darwin’s thinking about ‘On the Origin of Species’. 1 Genome-scale phylogeny of birds.
Honesty requires that I confess to having seen none of these species. These species are visually very similar, with subtle differences in their tail patterns. These species are visually very similar, with subtle differences in their tail patterns. Females of both species are mostly coppery-brown, with red bellies.
And, as I have mentioned before , under-birded countries like Mexico provide lots of opportunities for amateur birders like me to make real contributions to science. After investigating the area between the towns of Araró and Andocutín, I soldiered on to the equally-small town of Iramuco. But obsessed I am. And it brought friends.
Originally considered monotypic, two species are now recognized. Drakensberg (or Orange-breasted) Rockjumper is a Drakensberg Mountain species whose range is shared with the tiny landlocked kingdom of Lesotho. Males of this species are more brightly colored in their non-breeding winter plumage. the Rockjumpers.
My birder’s brain struggled mightily to reconcile the odd shapes in the sky with any known species, but their call brought it all back. Gaily color-banded, I’ve no doubt each individual is well-known to science. When the fish rise to investigate, a split-second snap of the bill captures a meal. What a sight.
Our animal ambassadors embody the ideal that empathy for one animal can evolve into empathy for an entire species and ultimately for all species. Negotiation: Cultivating sensitive communication and cooperation with governments to open the door to visionary win-win solutions.
"We will be investigating the cause of this incident to try and prevent additional releases," she said. Isn't it ironic how these animals show their clear intelligence by learning how to open a door at the same time their fellow species members are being sacrificed to science?
In this study, published in the journal Proceedings of the National Academy of Sciences, a group of juvenile zebra finches was allowed to interact with an adult. That’s because, unlike this current work, past studies didn’t control for the time exposed to song and the presence of other birds.
Flight Paths traces the history of migratory research in nine chapters, starting with the earliest attempts to track birds, bird banding/ringing (which she traces back to Audubon), and ending with ‘community science’ projects such as Breeding Bird Surveys and eBird. THIS IMAGE NOT IN THE BOOK. Schulman, 2023.
The species was extinct, a vanished part of the vanishing prairie — and not for the first time. In the 1950s the species was unofficially regarded as extinct by most biologists, a small part lost in the general tumble and disarray of the entire ecosystem they’d inhabited. You couldn’t see it. But this is real life.
Sixteen species that have been recorded in the United States are covered: six Myiarchus flycatchers and ten Kingbird ( Tyrannus ) flycatchers. As with the first volume, I was surprised to see the inclusion of a species that has only been seen in the U.S. Introductory Material Sixteen species, 190 pages.
It feels good to start a post with some truly attractive birds – such as two species of broadbills. Strangely, there do not seem to be many papers on this species. In one paper , you can find fascinating sentences such as “The new species is most similar to D.
The field site I am assigned to is located in one of the most diverse ecosystems in the world and home to a particularly rich avifauna that numbers well over 500 species. Hundreds of riotously colored birds representing 14 species of macaws and parrots flock and frolic together in less than fifty meters of forest canopy.
Even if you don’t live in the summer range of a particular species, you may have opportunities to observe it while it passes through, especailly if you live in an active flyway, like I happen to. Because the ancestor of this species of bird migrated, and the migratory adaptation and all that entails were passed on.
The Common Swift , Apus apus , is the most widespread of all the world’s 114 swift species, breeding throughout much of Europe and far into Asia, and wintering in sub-Saharan Africa May is the quietest month, as the returning birds soon get down to the urgent business of breeding. Young, non-breeding Swifts investigating nest sites.
The first half describes the problem (why birds hit windows, the scale of the deaths, scientific research, what happens when birds strike windows) and the second half discusses what to do about it (community and worldwide education, window deterrent solutions, legal mandates and building codes, citizen science–what individuals can do).
He roots the theft in the history of collecting bird skins, in the brief life history of Edwin Rist, in the secretive world of classic fly tying, and in his own efforts to follow up on a police investigation that got the man but not all of the loot. In some cases, he took all adult males of the species or subspecies held by the museum.
Being lazy, a bunch of researchers used camera traps to investigate the species rather than following the birds directly (which would have had some health benefits). They found that the species is diurnal (well, using cameras, would they even have seen nightly activities?), ” Full iteration!
The species also has something of a criminal record – the HBW reports that “Black-throated T**s [have also been] observed to steal nesting material from other species in central China” ( original source ). Taking photos of such a rare species is a bit of a double-edged sword. ” Wow.
