Ageing and sexing the curonicus subspeciesof the Little Ringed Plover Charadrius dubius

Little Ringed Plover (Charadrius dubius) Science Article 3 abstract Data presented here concern the curonicus subspecies of the Little Ringed Plover Charadrius dubius and are based mainly on information from Central Europe and Africa gathered duringthe breeding, migration and wintering periods. Therefore these criteria should be applied to other Little Ringed Plover subspecies or curonicus […]

Provision of nest cages to reduce little ringed plover Charadrius dubius nest predation at Welney, Norfolk, England

Little Ringed Plover (Charadrius dubius) Science Article 2 abstract At a site in eastern England, wire mesh cages were placed over little ringed plover Charadrius dubiusnests to protect their eggs from predation. The adult birds continued incubating their eggs and no nestdesertions were attributed to cage placement. Protection with cages resulted in an increase inproductivity, […]

Spatial patterns in at-sea behaviour during spring migration by little gulls( Larus minutus) in the southeastern North Sea

Little Gull (Hydrocoloeus minutus) Science Article 1 abstract At-sea distribution of seabirds has been studied on different scales and with different focus in many parts of the world. However, factors and/or processes causing certain patterns are often not easily explained. This also holds true for fast migrating species of international conservation concern, such as the […]

Sex differences in Little Auk Alle alle parental care: transition from biparental to paternal-only care

Little Auk (Alle alle) Science Article 1 abstract Understanding differences in male and female care in biparental care systems can help interpret the selective pressures that shape parental strategies. We examined Little Auk Alle alle parental care at a breeding colony during the chick-rearing and fledging periods by conducting observations on marked, known-sex pairs, and […]

Parental condition, brood sex ratio and differential young survival:an experimental study in gulls ( Larus fuscus)

Lesser Black-backed Gull (Larus fuscus) Science Article 2 abstract Empirical evidence is growing that the offspring sex ratio in birds can be biased in relation to the body condition of parents during breeding. The sex ratio bias may come about because (1) the actual production of the two sexes may be skewed and/or (2) there […]

The nominate Lesser Black-backed Gull Larus fuscus fuscus, a gull with a tern-like feeding biology, and its recent decrease in northern Norway.

Lesser Black-backed Gull (Larus fuscus) Science Article 3 abstract In northern Norway, Larus fuscus fuscus feeds mainly offshore on the wing on pelagic fish and fishery discards. It avoids competition with other large gulls for concentrated stationary food sources such as garbage dumps and fish-factories. It is also inferior to the Herring Gull L. argentatus […]
