The diet of the Antarctic Shag during summer at Nelson Island, Antarctica

Article Abstract:

Fish comprise the main diet of the Antarctic Shag collected during summer at Nelson Island, Antarctica. This was found in an examination of 139 stomach contents of the Shag, which also yielded octopods, gammarids, euphausiids and polychaetes. Meanwhile, the dietary differences exhibited by male and female Shags, in relation to their prey's mass, size and frequency, have been attributed to differential prey selection related to sexual dimorphism, prey availability and different foraging depths. While female Shags usually foraged in the morning, the males prefer to forage at night.

Eurasian Hobby density, nest area occupancy, diet, and productivity in relation to intensive agriculture

Article Abstract:

It appears that various elements of the life history of the Eurasian Hobby allow this falcon to breed successfully in areas of intensive agriculture. Late breeding permits these birds to nest in periods of low human activity in cultivated fields. The ability to nest in small woodlots, lines of trees and even single trees boosts the availability of potential breeding sites. Flexibility of inter-nest spacing patterns allows more efficient use of unpredictably available crow nests and mature woodlots.
