Its been a hectic week already. Good tunes are key to survival.
it’s worse than it looks.
Climate Change Shifts Bird Migration—One Generation at a Time
Biologists unravel how warming weather causes some birds to migrate earlier.
In the last few decades birders and biologists alike have noticed that spring migration is changing. Species are arriving on their breeding grounds earlier each year. It’s clear there’s a link between climate change and shifting travel dates, but a new study reveals that individual black-tailed godwits are very consistent in their migratory timing, challenging assumptions about how warmer weather shifts behavior.
These leggy, reddish shorebirds winter in Spain and Portugal. They return to their Icelandic breeding grounds each spring, between mid-May and mid-April, often nesting a month after arrival. A team of biologists who closely track their movements have noted that the birds arrive two weeks earlier today than they did twenty years ago.
To figure out why, they first tackled the long-held assumption that balmier weather might trigger individual birds to take flight sooner each season. Poring over 14 years of records for 54 individual godwits, they discovered something curious: Each bird returned year after year on roughly the same day.Whatdid change was the birds’ nesting date.
Good advice from [Bekka](http://bikeyface.com/wp-content/uploads/2012/01/banner_alt3.jpg) (as usual).
Since it is getting dark earlier and earlier with each passing day I’ll repost this as a PSA!
Proper lighting is key!
DC has a better bluegrass station that Crested Butte. Something about that seems wrong.
Not sure how I missed the greatness that is Steve Martin playing banjo until just now.
