Why do thousands of bird photographers go to Bosque del Apache every November? Well the light is amazing. The vistas are wide open. And there are hundreds of thousands of sandhill cranes, snow geese, Ross's geese, and just about every kind of duck you can find in your field guide.
Furthermore, the birds are somewhat acclimated to humans along the refuge's causeways and the birds tend to have routines that they follow. This allows nature photographers, with their lenses as long as a Cooper Mini, to get in position to take some really, really, really nice bird pictures.
For bird photography pikers like me, Bosque is a paradise, too. I can take some shots of a cooperative bird, change my settings wildly, take some more pix, change again, check them out on the camera's screen, take some more. You get the scoop.
We had an afternoon off late in our week at Bosque and just when the light was perfect, we turned a corner on the Marsh Route and found a newly flooded field chock full of resting, foraging snow and Ross's geese. So we joined the skirmish line of bird photographers already in place, snapping away.
Soon the geese took off in a sudden fright. Then they returned. They kept coming and going for the next hour and I thanked the gods that I was not shooting film because I took more than 500 frames.
Here are some of the more acceptable results.
Spooking into flight.
A great chance to compare Ross's goose (L) with snow goose (R).
Coming back around to land in the flooded field again. This looks to me like the shots of the imprinted birds in Winged Migration.
While scanning with my spotting scope, I noticed a blue morph bird that looked quite small by comparison...
It was a blue morph Ross's goose--a very rare bird. I'd seen this morph before here at Bosque, but not for a while. Everybody was really excited to see this bird. We radioed the other van and got them over to see it.
A closer look at the rare creature. Check out the tiny head. Note, too, the head of the snow goose in the foremost foreground, showing the black grin line on the bill. Most of the other white birds in profile in this shot are normal Ross's geese (sans black grin lines on their much smaller pink bills).
