The paper presents breeding records of the barbastelle (Barbastella barbastellus) from the whole current territory of Poland, both published data from papers and conference abstracts, and unpublished data collected by the authors. Up to 1999, known locations of maternity colonies and sites where young or lactating females had been caught, were assigned to only five forest regions or 16 Universal Transverse Mercator (UTM) squares. The number of such sites has significantly increased since 2000. Breeding sites of barbastelle have now been recorded in all Polish forest regions in 68 UTM squares. Most of the barbastelle sites were located in forest stands with high proportions of beech and oak (65%, N=46), and/or old-growth forest (over 32%, N=23). The highest elevation of a breeding site was at about 500 m.a.s.l. This paper summarises new records of maternity colonies of barbastelles for the first time, as a preliminary step to develop a more comprehensive conservation and monitoring plan for this near-threatened species. © NwjZ, Oradea, Romania, 2015.

Roosting site selection by geese is a key factor for survival during migration and wintering. Birds should select sites that minimize thermoregulation demands and predation risk, and maximize foraging efficiency. We used data on the spatial location of geese roosting sites in Poland to compare landscape features and the conservation status of roosting and non-roosting sites at different scales ranging from 5 to 50 km. Logistic regression revealed that the sites selected by geese had larger waterbody size than non-selected sites, and surrounded by a smaller coverage of woodland at the scale of 50 km. They also were more often Natura 2000 sites. The most important factors positively affecting the abundance of geese were the size of waterbody and low coverage of artificial area (mostly urban) within a 50 km radius. Several further factors also influenced the roosting site selection. Regardless to the scale a large coverage of farmland (mostly rapeseed) positively affected roosting geese whereas forest coverage had a negative effect. Spatial hierarchical clustering analysis showed that the roosting sites were densely located in regions characterized by the most intensive agriculture. Farming intensity therefore seems to increase the abundance of geese, and consequently, to increase a possible conflict between goose conservation and food production. To alleviate the conflicts we delineated areas that may be most affected and where the conservation measures should be implemented first. As geese respond to environmental factors at different spatial scales this scale-dependency should be included in the conservation and management of goose populations. © 2015, The Ecological Society of Japan.

Urbanization is the most dynamic phenomenon worldwide and many species colonize urban environment. Some of these species became so abundant in towns and cities that they are regarded pests, are human health hazard, causes damage to buildings and affect other urban species. Therefore, it is important to understand how such successful colonizers utilize urban environment and which factors affects their population densities. One of such species is the most common urban pest bird in the world, the Feral Pigeon Columba livia var. domestica. The aim of this study was to investigate how local food resources and the composition of the urban landscape affects densities of Feral Pigeon in the city of Poznań (Western Poland). Three counts were made in summer 2010 in 60 0.5 km × 0.5 km plots (25 ha) distributed randomly across residential areas in the city. The density of pigeons showed significant spatial autocorrelation, both positive and negative one. The density of pigeons was highest in plots with more tall buildings (over four floors), a large number of human-related food resources, schools, and a high proportion of green space. The density of pigeons was lower in plots with a higher density of streets and located further from the city centre. The solution to the pigeon problem appears to be to plan residential areas with low-rise buildings. To control the number of pigeons in urban areas, we suggest preventing access to local food resources by using litter-bins that are inaccessible to animals. The public should also be educated to behave appropriately towards pigeons and refrain from feeding them intentionally.

European souslik (Spermophilus citellus) is an endangered species being the subject of reintroduction plan in some European countries, including Poland. It is important to obtain data about behavior of reintroduced species, especially a reaction to captivity of specimens prepared to release. The aim of this study was to evaluate influence of human exposure on sousliks behavior. Observed animals were kept in Poznań zoo in three enclosures. Two of them (called "high noise") were in part of the zoo available to the visitors, whereas one ("low noise") was in part closed for them. In "high noise" enclosures sousliks spent more time outside burrows and more specimens were present above ground. They also ate and ran more frequently in "high noise" enclosure, whereas emitted loud voices more often in the "low noise" one. In all enclosures more animals were present above grounds in absence of humans. Time spent by one souslik above ground was positively significantly correlated with the number of sousliks outside burrows. European sousliks observed in this study were used to humans and were less vigilant if they were exposed to permanent humans presence, but they did not become tamed and behave in a way similar to free living animals. © 2011 Wiley Periodicals, Inc.

Reintroductions are considered an important part of the action plans and recovery strategies of endangered ground squirrel species, but so far little is known about their proper methodology. We collected primary data on 12 European ground squirrel reintroduction projects carried out at 14 localities in the Czech Republic, Slovakia and Poland since 1989. We focused on seven methodological aspects of each reintroduction: selection of release site, method of releasing, date of releasing, origin of released animals, total number of released animals, mean number of released animals per season and reintroduction site management. The method of releasing was found to be the key factor in determining the settlement of animals at the target locality. Only soft releasing methods, i. e. the use of enclosures and/or artificial burrows, ensure that animals remain at the target locality. The other factors significantly determining reintroduction success are the number of released animals per season (at least 23 animals required) and the total number of released animals (a minimum of 60 individuals). Long-term management of the site and regular monitoring of the newly established population are necessary. Our recommendations, based on experience with the successes and failures of previous reintroductions, could largely improve the efficiency of future reintroductions of highly endangered species. © 2011 Springer-Verlag.
