Breeding conditions:
|
| We spent about 46 hours at this montane site located on the northern border of Noatak National Preserve. The landscape held snow only on northern exposures, but despite the large amount of available habitat, we encountered very few individuals of sixteen bird species. We encountered only two wader species during our stay, Wandering Tattler Heteroscelus incanus (2 individuals detected, calling) and Surfbird Aphriza virgata (one individual detected, calling); neither species were confirmed breeding. It is our impression, however, that our visit was timed during the peak period of display and territory establishment as most passerine detections were of singing or displaying males. We detected no sign of microtine rodents, but sighted Caribou Rangifer tarandus, Dall Sheep Ovis dalli, and Arctic ground squirrels Spermophilus parryii throughout the area. |
