Although knowledge of ring recovery rate is of crucial importance to establish demographic parameters, such as survival probability, this information is generally unknown for the dabbling ducks. The almost single existing value from the North Am[...]

Migration is known to be a bottleneck in the annual cycle of many birds, and its success can depend on the availability of stopovers along the migration route. Satellite tracking was used to identify migratory strategies and important stopovers [...]

Here, we describe genetic diversity of lekking and non-lekking populations of Black Grouse Tetrao tetrix in the mountains bordering the Czech Republic. In total, 250 individuals from eight lekking and eight non-lekking study sites were genotyped[...]

Berlin Tierpark has a breeding female of the dark form of Steller's Sea Eagle Haliaeetus pelagicus ("niger") . This is the first known specimen for about half a century and the first evidence that it is not a subspecies but just a colour phase.

Hematocrit, the proportion of blood volume occupied by packed red blood cells, is frequently used as an estimate of phenotypic condition. Some studies in birds, however, suggest that hematocrit might not always be a good estimate of condition. W[...]

The study of animal communication during predator encounters has provided insights into the function of kin selection, the ontogeny of vocal development, and the mechanism of predator recognition. Less attention has been devoted to the study of [...]

The Hazel Grouse (Bonasa bonasia) has suffered from habitat loss due to changes in forestry practices in many regions of Europe. The widespread conversion of structurally heterogeneous to uniform, single-layered stands has caused many of its pop[...]

The Mute Swan (Cygnus olor) is a protected species whose population has shown a dramatic demographic expansion over the last decades in France. Today, Mute Swans are suspected of causing damages to wetlands, partly through their territorial beha[...]

The Blue Swallow (Hirundo atrocaerulea) is a threatened intra-African migrant with breeding populations in three geographically disjunct regions. We analysed stable hydrogen, nitrogen and carbon isotope ratios in feather keratin to determine whe[...]

The feeding apparatus of Paleogene birds is rarely well-preserved. Here, we describe the earliest known pelican (early Oligocene, Luberon, southeastern France), with its almost complete beak. Morphologically identical to modern pelicans, the new[...]

Since 2000, a new management technique has been introduced to stop the rapid decline of grassland breeding shorebirds in the Netherlands, called 'mosaic management'. The most important difference from earlier Agri-Environment Schemes is that the[...]

Gloss is a striking characteristic of avian eggshells that may affect both egg recognition and clutch predation. Previously, gloss has proved difficult to quantify objectively. Newly developed handheld glossmeters seem to offer a solution. We ev[...]

The concept of optimal foraging has been used to show how animals can increase their fitness by actively regulating the ingestion of nutrients or by avoiding detrimental plant metabolites, such as alkaloids. There is, however, considerably less [...]

The physical characteristics of nest sites are thought to influence both the outcome of breeding attempts and breeding behavior in colonial seabirds. We examined the relationship between nest shelter in breeding Northern Fulmars (Fulmarus glacia[...]

Harsh weather in spring presents energetic challenges to birds during migration and upon reaching the breeding grounds, and yet, birds often arrive well before breeding begins. We studied a population of Eastern Kingbirds in eastern Oregon from [...]

Crested penguins (genus Eudyptes) present a unique reversed egg-size dimorphism and hatching asynchrony, with the larger second-laid egg (B-egg) hatching before the smaller first-laid egg (A-egg). Both a higher water vapour conductance and paren[...]

Avian frugivores may select fruit based on their seed loads and pulp-to-seed ratios, and this may have important implications for their role as seed dispersal agents. Consequently, the effect of different seed packaging was investigated in two r[...]

Kleptoparasitism is a well-known foraging tactic used opportunistically by many seabird species. However, little is known about this behaviour during the early stages of the breeding cycle and its effects on breeding performance. Here, we invest[...]
