Larus delawarensis

Posted 6 October 2014 by

Larus delawarensis -- ring-billed gull, Boulder, Colorado. There is right now a fairly large flock at Walden Ponds east of Boulder. They are too far away to get a picture, unless you like snapshots of an array of gray-and-white ellipses. But this one very kindly landed in a parking lot and posed long enough to enable this portrait.

But if it's in Colorado, why is it named for a state on the east coast? :D

Perhaps they migrated west - perhaps via the Oregon Trail.... http://en.wikipedia.org/wiki/Oregon_Trail

Only if they lost their way en route! From the map, that trail passes north of Colorado.

Hey, is that a Buteo jaimaicensis flying overhead? Must really be lost. Or perhaps European taxonomists named a lot of species after the place they got the first specimens from.

Well that surely was not the name "ADAM" of the Bible gave it! And the failed non-loneliness to be only with animals!

But say: I have never understood how Aeronautical Engineering can be so well achieved merely by Evolution!

So I have had to bury my mind and head in logic and pure logic!

A Canadian organic flying AVRO, needed much modelling, and stopped there! The was no re-production! What a joke!

Netayahooo of Israel, says as a favourite: " if it quacks as a duck, and looks like a duck, and flies like a duck, it has to be a duck...!" Really amazing! He forgot to say if it swims and floats like a "duck"...!

To process salt water, is what humans will need someday! Could be! The gold coast Australia already has a "petroleum" desalination plant, for fresh water supply...!
