Adoption of unrelated offspring by successful breeders is one form of brood mixing and alloparental care that is widespread among geese and other waterfowl. Biparental care and long-lasting family bonds in geese are likely to affect the costs an[...]

This paper reviews the main effects that building tidal power barrages would have on the bird populations using Britain's estuaries. The changes in the tidal prism that would occur after a tidal power barrage is built are discussed in the contex[...]

We measured nesting success of the Temminck's Stint Calidris temminckii along the Finnish Bothnian Bay coast during 19 breeding seasons (1983-2001) and conducted a population census (1999-2002). We found 105 pairs, showing a marked decline from [...]

Recent non-experimental evidence suggests that reciprocal altruism may be more common in nature than was previously thought. Here we present experimental evidence for mobbing behaviour as reciprocal altruism in breeding Pied Flycatchers Ficedula[...]

We studied the prebreeding moult and resulting plumage in a long-distance migrant sandpiper (Scolopacidae), the Great Knot Calidris tenuirostris, on the non-breeding grounds (northwest Australia), on arrival at the staging grounds after the firs[...]

The African Penguin Spheniscus demersus (Vulnerable) formed three new colonies during the 1980s, two on the South African mainland (Stony Point and Boulders) and one on Robben Island. One of the mainland colonies, at Boulders, Simon's Town, is i[...]

We studied the post-juvenile dispersal of 18 radiotagged juvenile Hazel Grouse Bonasa bonasia (14 males, four females) in an expanding population in the southeastern French Alps between 1998 and 2001. The mean dispersal distances between the cap[...]

The habitat copying hypothesis states that animals use the reproductive performance of conspecifics to evaluate habitat quality and choose their future breeding site. We used data from Audouin's Gull Larus audouinii (1992-2003), a species adapte[...]

Nest predation is an important determinant of owl breeding success. We studied Long-eared Owl Asio otus productivity and attributes of nest-sites at the microhabitat and landscape scales in a Mediterranean locality over an 8-year period. We exam[...]

We describe the sequence and extent of the complex and little understood post-juvenile and post-breeding moults of Savi's Warblers Locustella luscinioides. In contrast to previous studies, the post-juvenile moult occurred in at least 44% of the [...]

We looked for evidence of a cost of reproduction in the Marsh Tit Parus palustris living in the last fragments of primeval temperate forest (Bialowieza National Park, eastern Poland). Potential nest-holes were superabundant but the birds had to [...]

The Norwegian Greylag Goose Anser anser population has been increasing steadily over the past few decades, causing increasing nuisance in terms of agricultural crop damage. This, in combination with the importance of Greylags as a hunting target[...]

To investigate the covariation of adult body condition and nestling growth, we weighed adult Brunnich's Guillemots Uria lomvia rearing chicks at Coats Island, Nunavut, Canada, each year between 1988 and 2002. We estimated chick mass at 14 days f[...]

We examined the relative contributions of egg size, parental quality and hatch-date to growth and survival of second-hatched chicks (those chicks making the greatest contribution to differences in productivity among pairs) by exchanging clutches[...]

During the highest spring tides the intertidal sediment flats of estuaries are fully inundated at high water, and waders have no choice but to move to supratidal roosts, e.g. on open farmland, saltpans or beaches. However, in many estuaries duri[...]

We examined regional and temporal variations in prey selection by Golden Eagles Aquila chrysaetos during the nestling period in Japan. We made direct video recordings of a pair of Golden Eagles in Akita prefecture as they delivered prey to the n[...]
