Long-distance Migrants and Hitchhikers
I’m currently on board the NOAA Ship Oscar Dyson in the Bering Sea. The last few days in the eastern Bering Sea have produced some interesting birds. In addition to the usual variety of tubenoses, alcids and larids a number of southbound migrants have passed the ship this week. Some are birds that have adapted to long, non-stop ocean crossings, others are not…
Bristle-thighed Curlew Numenius tahitiensis, Eastern Bering Sea, 30 August 2010.
Highlighting the list of fly-by appearances was this lone Bristle-thighed Curlew. It flew in to the stern of the ship, checked us out, gave a few whistles and flew off. Although the pictures are marginal you can still make out the warm tones to the underparts and the diagnostic mark–the peach-colored rump which appears contrastingly pale in the last photo.
Ruddy Turnstone Arenaria interpres, Eastern Bering Sea, 30 August 2010.
Ruddy Turnstones have been regular this week with at least one small flock approaching the ship every day. Today (8/30) we recorded over 20 individuals in several small flocks. Other shorebirds seen from the ship today were Pacific Golden-Plovers (4), Bristle-thighed Curlew (1), and Red Phalarope (100′s). Three Wandering Tattlers have flown by the trip since the we left Dutch Harbor on 17 August. Mind-boggling to think that the tattlers, turnstones, plovers and curlew may be in Hawaii or further before this ship get’s back to Dutch Harbor!
A Piscivorous Golden-crowned Sparrow Zonotrichia atricapilla, on board the Oscar Dyson in the Eastern Bering Sea 30 August 2010.
This Golden-crowned Sparrow landed on the ship on yesterday and was still here today. He’s been eating, or attempting to eat, juvenile Pacific sand lance Amodites hexapterus which the NOAA scientists have been catching on their surveys. A new food item for the species?
Orange-crowned Warbler Oreothlypis celata, Eastern Bering Sea, 25 August 2010.
This Orange-crowned Warbler only spent a few hours on board. (Note the change to the genus. Click here for info on other changes and updates to the AOU checklist.)
