Anyone Want to Try VisMig this Year ??

Anyone fancy learning about and having a dabble at counting Visible Migration at our "Members Only Reservoir" (see Mark Doveston for keys and access details, you need to be a current member of BOG). If so Howard and myself are about up there early doors Saturdays and Sundays weather permitting for the rest of the vis season. Scope, bins, possibly a deck chair and a very warm hat / coat required!!! Its not always a mega move of birds every day but if you just hit that "good" day you may well be hooked for life..... heres what we had yesterday (Saturday 30th August.... a good start to the season). Usually we pack it in about 1030hr unless it seems to be worth staying!

Mountain, Queensbury.... HAZE (c) 2008

Linnets on the Move. (c) 2008

0710 - 1230hr
DB / HC
Calm - SSE F1 rising SE F5, 17degC initially, 5.5km, 8/8 2500ft, Dry, QNH 1018 falling.

After yesterdays taste of autumn, a "real do" this morning with not only the birds on the move south and west as the wind picked up but hundreds, yes hundreds of bombus sp, a few migrant moths and even a couple of dragonflies all powering WNW on the wind. Chaffinch were the first movers (must be dispersal at this time of year?) to become apparent with flocks of up to nine powering hard south, just like October! Mipits were few and far between but all were going west with just a few blogging in the sand pits. Linnets were phenominal with a total of 304 counted including a massive flock (thought to be disturbed by a raptor) of 0ver 200 with the majority going south. A loose group of four Tree Pipits passed SW with much "tzee" ing at 1015. a Peregrine powered purposefully south at 1054. A moderate group of Canadas were fresh back and included in the flock were a Barnacle and a Pinkfoot!!! origin doubtfull but nevertheless here!!****. (****Just heard that the first pinkies were back at Martin Mere on 29th August so there is a chance that this bird was part of the first arrival wave!). A total of three Sparrowhawks went west. Later in the morning very large numers of Gulls started appearing very high from the north, many overflew hard south but a few dropped down to the water.... we diddnt start counting the gulls until later so the numbers are an under representation as to the actual magnitude of the move.

Can anyone confirm the id of the Bumblebees from the snaps below.... the two appeared to be mating but there were hundreds on the move. Does anyone know anything about the moves / migrations? of these bees as they were really exciting this morning!

They look like white-tailed to me, but check with the Bumblebee Conservation Trust. Email pics with date, grid ref or postcode to g.c.lye@stirling.ac.uk, or see their website.

Thanks for that Sally, I will contact the BBCT re both this which I also believe to be white tailed and also the potential "bilberry", photographs below. I will post the results here in due course.

Again, many thanks,
Dave.

Hi Dave,
I think Gillian Lye must be away as I'm also waiting for a reply. You could try: dave.goulson@stir.ac.uk, also of the BBCT.
