Ringed Plover Charadrius hiaticula and Kentish Plover Charadrius alexandrinus are typical species of the Delta area, southwest Netherlands. A major part of the Dutch breeding populations of both species occurs in this area. One of the aims of th[...]

Overwintering Coots Fulica utra atra were observed in January 2006, in Keoladeo National Park, India. Here they fed on aquatic plants, which they exploited in strictly-maintained dense flotillas; these flocks behaved like a super-organism. This [...]

We measured parental care (attendance patterns, foraging trip durations and meal sizes) and chick growth patterns in 45-54 pairs of Little Penguins Eudyptula minor at a breeding colony in southeast Australia during five breeding seasons. Chick s[...]

Local populations in marginal habitats close to the distribution border are expected to vary more in size than central populations. To obtain information on the viability of metapopulations, monitoring in peripheral habitats might therefore be a[...]

The selection of an appropriate site for nesting is of vital importance in birds, especially in ground nesting species as Montagu's Harrier Circus pygargus. This raptor mainly uses cereal crops as nesting habitat, although natural vegetation is [...]

The Northern Goshawk Accipiter gentilis typically prefers woodland habitat for nesting and hunting. In recent decades, however, the species has started colonising urban environments across Europe. Here I present the first study on the ranging be[...]

The conservation and management of wild goose populations requires an accurate estimate of productivity to be made each year, usually soon after the birds' arrival in the wintering grounds. The best time to make the estimates is not always clear[...]
