Caspian Terns, Hydroprogne caspia, congregating atop a waterfront warehouse roof in Astoria, Oregon.
There is quite a significant colony of these birds in the Astoria area, a portion of which have taken to gathering on the rooftop of one of the buildings owned by Astoria Warehousing along the town’s waterfront. While birds on a rooftop are not normally that difficult to photograph, the nearly flat roof made it necessary to position myself at quite a distance away in order to get a clear image of the birds. This image was recorded while I was standing on an old railroad trestle bridge that crosses the now flooded site of a nearby former fish cannery.
Digiscoped image with the spotting scope eyepiece set at its highest (50x) magnification level.
Equipment:
Canon PowerShot SD1100 IS camera
Swarovski ATS 80 HD spotting scope
Swarovski 25-50x W eyepiece
Swarovski UCA (Universal Camera Adapter)
Swarovski Carbon CT101 tripod
