Effects of water quality on habitat use by lesser scaup (,) broods in the boreal Northwest Territoriitat preferences of lesser scaup broods by comparing water quality, physical features and invertebrate abundance in natural ponds and borrow pits that were used or avoided by brood-rearing lesser scaup. Twenty eight water quality, physical and biotic characteristics of ponds were measured in the fielobster 发表于 2025-3-25 09:08:47
Diurnal time-activity budgets of redheads (,) wintering in seagrass beds and coastal ponds in Louisina showed increased resting and decreased feeding as winter progressed, but redheads in Texas did not exhibit a seasonal pattern in either resting or feeding. In Louisiana, birds maintained a high level of feeding activity during the early morning throughout the winter, whereas afternoon feeding tap金桌活画面 发表于 2025-3-25 12:59:22
Foraging behavior of redheads (,) wintering in Texas and Louisiana same level as that shown by redheads foraging in the upper Laguna Madre. The overall foraging level of redheads from Chandeleur Sound was greater (41%) than that of redheads in the upper Laguna Madre (26%), yet it was quite similar to the 46% foraging level reported for redheads from the lower Lagu小歌剧 发表于 2025-3-25 17:26:55

Breeding waterbird wetland habitat availability and response to water-level management in Saint Johnds respectively. The overall density of waterfowl broods was greater on impoundments than on seasonally flooded wetlands during both years of study but varied by site. Mean species richness of wetland obligate birds was significantly greater on impoundments than on seasonally flooded wetland habitatCapitulate 发表于 2025-3-26 02:29:23
Populations of ducks and trout of the River LaxÁ, Iceland, in relation to variation in food resourceay have affected spring numbers and dispersion of harlequin ducks, but the evidence was not conclusive. Numbers of both duck species and the trout (as CPUE) were relatively stable, although a sharp drop in numbers followed by slow recovery was observed in Barrow’s goldeneye, and an increase was obseDefraud 发表于 2025-3-26 05:29:00
