Six microsatellite loci were isolated from the petrels of Round Island, near Mauritius in the Indian Ocean (Pterodroma arminjoniana). Three loci were monomorphic in P. arminjoniana but were found to be polymorphic in other Procellariiforms. Cros[...]

The Sichuan Treecreeper, Certhia tianquanensis Li 1995, was recently recognized as an independent species. Apparently, it is an endemic relict occupying an extremely small range in western Sichuan and Shaanxi provinces, China. During April-July [...]

We isolated seven novel polymorphic microsatellite DNA loci from the burrowing parrot (Cyanoliseus patagonus) and optimised them for future studies of population differentiation and genetic variation. The loci were screened for polymorphism usin[...]

Farmland birds in Central Europe have been heavily declining in past decades. Among them are many ground-nesting species, adapted to semi-natural but secondary habitats. A vivid example is the Black Grouse (Tetrao tetrix) in the lowlands of nort[...]

A nationwide volunteer survey was conducted to investigate the time at which common species of birds arrived at garden feeders in the morning during winter, and over 5,800 participants submitted observations. We examined the relationship between[...]

Alarm calls given by parents when risk is detected during nesting may be considered a form of parental defense. We analyzed variations in callings of breeding pairs of the Southern House Wren Troglodytes musculus during the nesting cycle and whe[...]

Trends in the onset of breeding, clutch size and numbers of hatchlings and fledglings are examined for a Mediterranean montane population of Blue Tits (Cyanistes caeruleus) subject to recent warming in springtime monitored during 20 years. Blue [...]

The relationships between breeding site location in forest habitat and age, behaviour and reproductive performance of Blue-footed Boobies Sula nebouxii were examined in two different plots on the northeast corner of Isla Isabel, Mexico. Birds ne[...]

We describe a unique, hand-coloured copy of Ray's (1678) The Ornithology of Francis Willughby that was apparently presented to Samuel Pepys between 1684 and 1686 during his presidency of the Royal Society. Somehow, this volume was not catalogued[...]

In many birds, the male reproductive tract is asymmetric with the left testis being larger than the right one. Coucals (Centropodidae) represent an exception as the asymmetry is typically reversed. Here, we describe the functional morphology of [...]

Most of the known food webs are based on organic compounds provided by photoautotrophic organisms. The terrestrial ecosystem of Malpelo Island (Colombia) seems to be an exception, however, since it supports several trophic guilds without hosting[...]

We provide evidence for cooperative breeding in two endemic parrot species of New Caledonia, the New Caledonian Parakeet (Cyanoramphus saisseti) and the Horned Parakeet (Eunymphicus cornutus). We intensively monitored 11 breeding attempts in two[...]

Vocal communication in duetting and chorusing birds is a growing area of study in avian ecology, yet much remains unknown about temporal and population-level variation in these complex vocal signals. In this study, we describe the acoustic struc[...]

We examine sex ratio variation and sex-specific probability of successful fledgling in relation to hatching date across 376 broods of Great Reed Warblers (Acrocephalus arundinaceus). The sex ratio of complete broods as well as broods with partia[...]

Human activities may restrict access of wintering birds to their food resources, but habitat destruction and fragmentation may interact with disturbance to reduce carrying capacity. We analysed the abundance and distribution of wintering Brent G[...]

A relict colony of Northern Bald Ibis (Geronticus eremita), a critically endangered species, was unexpectedly discovered in Syria in 2002. During six subsequent breeding seasons (2002-2007), the 3, and then 2, breeding pairs of Northern Bald Ibi[...]

The Hazel Grouse Bonasa bonasia is strongly affected by forest dynamics, and populations in many areas within Europe are declining. As a result of the 'wilding' concept implemented in the National Park Bavarian Forest, this area is one of the re[...]
