So small, birds can seem so
vulnerable. And yet these beautiful,
winged, often tuneful descendants of dinosaurs have proven able to cope with
conditions that would baffle or defeat us.
Much like sharks, another ancient
breed, birds survived after dinosaurs and others went extinct and after drastic
environment changes. But, like sharks,
they’re now seriously threatened . . . by humans.

Their survival, one theory has it, occurred because they were small, could eat a variety of foods and could fly. But now, population numbers have declined by around 3 billion birds in North America during the last 50 years alone. http://tinyurl.com/mr385vxu and http://tinyurl.com/2p9d6tmr

First, back to that concern about how birds survive major storms. Their methods are surprising. A large percentage of birds are migratory, which helps, as does their ability to detect and “read” air pressure system changes, then react accordingly. http://tinyurl.com/3px7wz2z
However, even in migrating, birds face obstacles, starting with habitat losses along the way http://tinyurl.com/54dme94m and modern hazards, like building lights at night, which can attract them and cause fatal or debilitating window strikes. http://tinyurl.com/sp9c3s2f

Then this sadly familiar fact about
birds: As is true in human life, birds too are sometimes the victims of sexism
in science. Male specimen birds have
been found to prevail in 5 respected natural history museums, often accompanied
by denigrating assumptions about female birds that were reached because of
incomplete study. http://tinyurl.com/yezzh2cd
In short, “Half of all birds are females, yet they have long been overlooked in ornithology.” (And yes, steps are underway to correct this practice of sex-skewing!)

Further, I’ve been delighted to learn
that love still actively lives between 2 long-separated macaws in Brazil. For decades now, one bird regularly visits
the other and they commune between the netting that keeps them apart. I challenge you to read their story without
welling up. http://tinyurl.com/2vjbu7yv

Stale bread with soup: wouldn’t you dip the bread to make it more palatable? That’s just what these white parrots also do with their dry, twice-baked toast and water every day at lunch -- and they’re the first known to do so. (Shades of our tendency to dunk biscotti!) http://tinyurl.com/mr2jyjax

Starting this year, the re-naming process
will be carried out by the American Ornithological Society, and affect around 150
birds, some now named for racists, slaveholders and others now in disrepute. As the admired writer of the article linked
here says, “If renaming the birds
becomes part of a broad reorientation toward nature itself, it’s a symbolic
gesture that could be the start of saving it all. The birds and us.” http://tinyurl.com/5cys36fs
It's shocking how the bird population has declined (along with the insects, the fish, and the mammals) and I hope we can support scientists who are studying ways of changing this trend.
