We started August with new arrival to our publications. David Diez-Méndez with his colleagues studied the composition of nest material in three species of tits. He found that Blue Tits made greater use of bark, feathers and vegetable fiber, while Great Tits used wild boar hair in greater proportions. In addition, for the first time, he described in detail the nest composition of Coal Tits, which contained large amounts of fluff compared to the other two species. These results confirmed existence of species-specific characteristics in the selection of material for nest building; so the closely related birds avoid competition for material.

Congratulation!
