false feedings at the nests of Carrion Crows corvus corone corone
Behavioral Ecology and Sociobiology, 2004Co-Authors: Vittorio Baglione, Daniela Canestrari, Jose M MarcosAbstract:False feedings, when individuals visit the nest but refrain from feeding the chicks, occur in some cooperative species and have been interpreted in the white-winged chough (Corcorax melanorhamphos) as active deception by helpers towards the rest of the group. In a cooperatively breeding population of Carrion Crows (Corvus corone corone) 81.5% of the individuals that provided nestling care showed various kinds of false feedings: arriving at the nest with no food, consuming part or all the food brought to the nest, or taking back from a chick’s gape the food that had just been delivered. False feedings occurred on average during 16.3% of nest visits, with some individuals performing them at very high rates (up to 64% of nest visits). False feedings occurred at similar rates in unassisted pairs and groups with helpers, and breeding females showed false feeding at significantly higher rates than other group members. Furthermore, individuals showed false feedings regardless of whether they were alone on the nest or in the presence of other group members, and false feedings did not provoke aggression by the rest of the group. False feedings are not likely to represent deceptive help in the Carrion Crow. We suggest that Crows evaluate the chicks’ condition during nest visits and that false feedings occur as result of a trade-off between their own hunger and the chicks’ needs.

history environment and social behaviour experimentally induced cooperative breeding in the Carrion Crow
Proceedings of The Royal Society B: Biological Sciences, 2002Co-Authors: Vittorio Baglione, Michael Griesser, Daniela Canestrari, Jose M Marcos, Jan EkmanAbstract:Kin-based cooperative breeding, where grown offspring delay natal dispersal and help their parents to rear new young, has a long history in some avian lineages. Family formation and helping behaviour in extant populations may therefore simply represent the retention of ancestral features, tolerated under current conditions, rather than a current adaptive process driven by environmental factors. Separating these two possibilities challenges evolutionary biologists because of the tight coupling that normally exists between phylogeny and the environmental distribution of species and populations. The Carrion Crow Corvus corone corone, which exhibits extreme interpopulational variation in the extent of cooperative breeding, with populations showing no delayed dispersal and helping at all, provides a unique opportunity for an experimental approach. Here we show that offspring of non-cooperative Carrion Crows from Switzerland will remain on the natal territory and express helping behaviour when raised in a cooperative population in Spain. When we transferred Carrion Crow eggs from Switzerland to Spain, five out of six transplanted juveniles delayed dispersal, and two of those became helpers in the following breeding season. Our results provide compelling experimental evidence of the causal relationship between current environmental conditions and expression of cooperative behaviour.

COOPERATIVELY BREEDING GROUPS OF Carrion Crow(CORVUS CORONE CORONE) IN NORTHERN SPAIN
The Auk, 2002Co-Authors: Vittorio Baglione, Jose M Marcos, Daniela CanestrariAbstract:Abstract The Carrion Crow (Corvus corone) is almost invariably reported as a species breeding as unassisted pairs, but a population of Carrion Crows (Corvus c. corone) from northern Spain that we have been studying since 1995 regularly exhibits cooperative breeding. The Spanish population thus demonstrates that cooperative breeding can vary greatly across populations. Most of the breeding territories (73.3%) in Spain were held by cohesive groups, which consisted of up to nine birds (mode = 3 birds). The proportion of fledglings that delayed dispersal for one year varied between 12.2 and 47.5% for different cohorts. The corresponding values for juveniles postponing dispersal for two years were 4.9 and 19.2%. Philopatry was skewed toward males. Some social groups contained immigrants. Therefore, delayed juvenile dispersal was not the only route towards sociality. Up to three helpers provided food to the nestling and at least one helper was found in all the groups surveyed. However, some group members refrai...

adoptions in a coδoperative population of Carrion Crow corvus corone corone
Bird Study, 2003Co-Authors: Jose M Marcos, Vittorio BaglioneAbstract:Capsule Adoptions occurred at low rate (2.6% of successful nests and 1.1% of fledglings), probably as a result of a mistake in early offspring recognition.

serologic evidence of west nile virus and usutu virus infections in eurasian coots in the netherlands
Zoonoses and Public Health, 2018Co-Authors: M Geervliet, Gerard J D M Muskens, Albertus D M E Osterhaus, Josanne H. Verhagen, Byron E. E. Martina, Frank A MajoorAbstract:Summary West Nile virus (WNV) and Usutu virus (USUV) are arboviruses that are maintained in enzootic transmission cycles between mosquitoes and birds and are occasionally transmitted to mammals. As arboviruses are currently expanding their geographic range and emerging in often unpredictable locations, surveillance is considered an important element of preparedness. To determine whether sera collected from resident and migratory birds in the Netherlands as part of avian influenza surveillance would also represent an effective source for proactive arbovirus surveillance, a random selection of such sera was screened for WNV antibodies using a commercial ELISA. In addition, sera of jackdaws and Carrion Crows captured for previous experimental infection studies were added to the selection. Of the 265 screened serum samples, 27 were found to be WNV–antibody-positive, and subsequent cross-neutralization experiments using WNV and USUV confirmed that five serum samples were positive for only WNV-neutralizing antibodies and seven for only USUV. The positive birds consisted of four Eurasian coots (Fulica atra) and one Carrion Crow (Corvus corone) for WNV, of which the latter may suggest local presence of the virus, and only Eurasian coots for USUV. As a result, the screening of a small selection of serum samples originally collected for avian influenza surveillance demonstrated a seroprevalence of 1.6% for WNV and 2.8% for USUV, suggesting that this sustained infrastructure could serve as a useful source for future surveillance of arboviruses such as WNV and USUV in the Netherlands.
