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