“…It also gives an opportunity to control bird flocks which may otherwise destroy part of the harvest (Whittingham et al, 2001;Paralikidis et al, 2009). The chaffinch is known as a distributor of seeds of wild plants (zoochory) (Heleno et al, 2010;Perea & Gil, 2014).…”

The сhaffinch (Fringilla coelebs Linnaeus, 1758; Passeriformes, Fringillidae) is one of the most colourful forest species of birds living in Europe, West Asia and North Africa. The diet of this species was studied as a contribution to the conservation of the population of this species in transformed forests of the north-eastern part of Ukraine. Four forest ecosystems were studied: three model sites in oak forests, transformed under intensive recreation pressure, and one model site in a pine-oak forest. A total of 39 invertebrate taxa, dominated by Insecta (93.0%) were found. The orders Coleoptera (32.6%) and Lepidoptera (63.5%) prevailed in the diet of finch nestlings, the highest number of taxa (52.3–76.2%) was represented by phytophages. The phytophagous species also constituted the majority of the consumed prey items (44.0–55.6%). Environmental conditions provided an important effect on the diet structure. The most favourable foraging conditions for the species were found in protected natural areas. According to the analysis, the finch foraging efficiency was similar in all the studied sites. The highest biodiversity indices were found in a protected area of Homilshanski Forests National Nature Park. Results of the research have indicated the crucial role of Fringilla coelebs in the population management of potentially dangerous agricultural pests.

“…It has been found in other species that the outcome of interspecific competition during winter may reflect the situation during the breeding season (Dhondt and Eyckerman 1980). Thus, it is possible that the dominance hierarchy between finches at a garden feeder during winter accounts for the spatial segregation of species while they are foraging together (Perea et al 2014).

“…We focussed on three finch species of similar body and bill structures, but of different sizes: large-hawfinch (Coccothraustes coccothraustes, average total body length = 17.5 cm), medium-greenfinch (Chloris chloris, 15.5 cm) and small-goldfinch (Carduelis carduelis, 13.5 cm) (Svensson et al 2010). Although direct observations of competition between these species have not been reported so far, the three species are expected to interact antagonistically owing to their similar dietary preferences (granivorous), especially in winter, when they gather in mixed flocks (Perea et al 2014). We expected to find a hierarchical dominance among the species in relation to body size, with larger species outcompeting smaller ones.…”

Interspecific agonistic interactions are important selective factors for maintaining ecological niches of different species, but their outcome is difficult to predict a priori. Here, we examined the direction and intensity of interspecific interactions in an assemblage of small passerines at a garden feeder, focussing on three finch species of various body sizes. We found that large and mediumsized birds usually initiated and won agonistic interactions with smaller species. Also, the frequency of fights increased with decreasing differences in body size between the participants. Finally, the probability of engaging in a fight increased with the number of birds at the feeder.

“…Last of the spring seed producing trees are P. deltoides and Salix species because they are specialized to colonizing the most flood prone surfaces on new bars (Marks, unpublished data). Both avian and small mammal granivores consume elm seeds (Dulamsuren et al 2009;Erritzoe 2010;Hulme and Hunt 1999;Perea et al 2013Perea et al , 2014Venturas et al 2014).…”
