Cabot Tower BSG Launch

Sunday morning (2nd Oct) was our first official visible migration watch from Cabot Tower. In between the introductions, pictures, interviews and general chit-chat, we managed to get in a bit of birding and had some good sightings of migrant passerines (often flying right past us at eye-level) heading south over Bristol.

9 of us, including myself, Ed Drewitt and David Lindo (The Urban Birder) were in attendance. We weren’t expecting any significant movement after the extended spell of good weather, light winds, lack of cloud and average visibility – but we had lots more finch movement than previously (including our first siskins and larger groups of migrant chaffinches), plenty of pied / white wagtails (but fewer grey wags) and as usual, a patchy but consistent stream of meadow pipits.

The session lasted c2hrs from 6:45, but all counts are conservative, due to a general lack of vigilance by myself whilst discussing the project etc. during the inaugural session. All movement generally south unless stated otherwise:

meadow pipit – 130 (at least with largest group of 30)

pied / white wagtail – 61

chaffinch – 52 (largest group 15)

siskin – c30 (largest group 8)

goldfinch – 32

A few other bits moving south including a couple of starlings, collared doves and greenfinch, but no significant numbers. No hirundines.

Other sightings (non-migrants) were 8 ravens close by, with a few distant groups of 2 or 3 to the north-west, a pair of adult peregrine (possibly Gorge pair due to size of female) on Clifton Catholic Cathedral and an extremely close sighting of a sparrowhawk flying directly towards the tower, lit from underneath by the early morning sun.

The next session will be in the coming week depending on the weather and planned Tower 42 meetings, and we are hoping for higher numbers of finches and our first redwings of the autumn.

Thanks to Ed D, Ed F, David, Tina, Alex, Liz A, Liz S and Pete for making it not only a success but plenty of fun too.
