Effects of fire on golden eagle territory occupancy and reproductive success

Article Abstract:

There have been large losses of shrub habitat as a result of fires in southwestern Idaho, and this has affected the jackrabbit population, in turn affecting golden eagles. Major fires led to a drop in the success rate of golden eagle pairs, though pairs had a higher success rate if they could expand their territory, and this could lead them to be as successful as eagles in areas unaffected by fire. The success rate prior to the fires was also important. There should be an effort to prevent fires and rehabilitate land after fires have occurred.

Hand-rearing corvids for reintroduction: importance of feeding regime, nestling growth, and dominance

Article Abstract:

Endangered corvids were hand-reared on 14 feeding regimes to explore their health, growth and survival. Combinations of large amounts of food and frequent feeding produced fast-growing, heavy birds with few fault bars in their feathers. However, hand-reared chicks grew more slowly than wild-reared chicks. Frequency of feeding affected growth and survival more than initial amount of food in small- to medium-sized passerines. In large passerines, initial amount of food offered affected growth and survival more than frequency of feeding.

Responses of American crow populations to campgrounds in remote native forest landscapes

Article Abstract:

The effect of campgrounds on the American crow (Corvus brachyhynchos) populations, which are potential nest predators for marbled murrelets, on the Olympic Peninsula in Washington, USA is analyzed. Observations suggest that crows may indicate the suitability of campgrounds to other human commensals.
