Small arboreal vertebrates usually avoid using large tree cavities for breeding because of predation risk.
However, my #cameratrap observations showed that large cavities are still attractive sites for feeding, resting, or social interactions.

On our local study plot in E Ukraine, #aspen stands were especially important for settling birds.
Such stands descend from improper reafforestation on industrial clear-cuts made in the mid-20th century. Now in a protected area, they are full of canopy gaps and emerging deadwood

Black Woodpecker range in E Europe contracted to the north in the early 20th century. In recent ~50 years, they have been expanding to the south again. It could be driven by changes in logging intensity and maturation of forest plantations in the region

A rare footage of tawny owl attempting to hunt squirrel. Seems to be unsuccessful.
Not a common prey for this species.

This is about our long-term bat studies in Kharkiv region, Ukraine. I am wondering when it would be possible to survey many of these territories again.

Bat diversity and abundance are highest in old deciduous #forest stands on river banks in Eastern Ukraine https://t.co/D2bigPDTko https://t.co/tbDWN9YCT1

@gow_derek @woodlandbirder @actaorn Rather elks (Alces). They leave similar feeding signs

[yyatsiuk @yyatsiuk]

Black woodpecker covered with Myrmica #ants, probably after feeding on their nests. Quite common situation in my #cameratrap study. Seems that they are not bothered.

I was helping @yyatsiuk to check 📷 traps during the spring. Now I can boast a selfie with a woodpecker #ornithology #ecology

@maysays Not even animal as large as human)

Hornet Wasps are especially abundant on my study plot this year. Look how they drive away other visitors.

@AnEtchabear @wildlifeni As I understand, there were just imitations of attacks and it was enough for birds/squirrel. At least, contacts were too short to allow wasps to inject a lot.

[yyatsiuk @yyatsiuk]

@madthrush Probably yes. I don't know if other such a large wasps lives here
