Nature Notes: Wittenbergener Heide

the Wittenbergener Lighthouse marks the starting point of our trip through the Wittengbergener Heide, a nature reserve in Hamburg that includes inland dunes, heath and light forest.

a spider cocoon (I think) from last year

there were many of those holes in the dune area - we didn't see what made them, but I suspect Typhaeus typhoeus, a species of dung beetle that builds tunnel of up to 1.5 metres and feeds its larvae with rabbit dung

a view over the heather, right after we were screamed at by a group of 15 Eurasian Jays (Garrulus glandarius)

Eurasian nuthatch
a Eurasian Nuthatch (Sitta europaea), making it clear to everybody that this was his territory

You can listen to a call here

the view over the Elbe - the opposite shore is the island Neßsand

horse ant
a horse ant (Formica rufa), it's quite a big species with workers measuring 5-9mm and queens 9-11mm

sand bee
a sand bee, I think Andrena cineraria / Ashy Mining Bee, but I'm not 100% sure. It was warming up and not yet ready to fly.
