This one, deservedly, is wholly ‘for the birds’

California Condor
Hours of torrential rain, often with high winds.  Day-long snowfall with intense cold.  How and where do the birds shelter? 

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.

Tufted titmouse
Today, largely unaware of their long history that includes 150-million-year-old bird fossils, we take birds for granted.  They started out as feathered small, meat-eating dinosaurs (theropods) with sharp teeth that over time evolved into beaks.  

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

Given the estimated 11,000 bird species in the world, it’s impossible to imagine the great variety that must exist among them.  But this look at some of the birds mentioned lately in the media might suggest the possibilities – and enhance the respect. There’s much more to say about birds than the common advice in health and fitness articles – listen to bird song and feel better.   

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

Pelicans & pouches
Whether stay-at-homes or travelers, birds are also affected by temperature changes, particularly severe cold snaps that can lessen survival rates of new-born hatchlings. One for-instance: cold kills nsects, so parent birds can only scout up less food for their young.

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!)

Hawk
I'm not a “birder,” in the usual sense of the word, but more and more I’m intrigued by news about birds – such as word that a particular woodpecker may not be extinct after all (http://tinyurl.com/2hxar8k6 ) or that near New Zealand’s capital, conservation efforts succeeded in the hatching of kiwi eggs in the wild for “the first time in living memory.”    http://tinyurl.com/2ebhhpy6

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

Chickadee
Vultures.  Did you “Ugh!” at that word alone?  Both their looks and their job of carrion-eating can prompt such reactions.  But read this story and learn how very smart these birds are in pursuing their scavenging occupation – using their “wide-angle intelligence.”       http://tinyurl.com/2y8hvnum

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

Seabird
Birds are such varied and fascinating creatures, we may all be happy about plans to improve on their North American names – to focus “attention on the unique features and beauty of the birds themselves,” rather than keeping names with “associations with the past that continue to be exclusionary and harmful today.”

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

  1. 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.
