Colin spent a good few hours at the reservoir this morning and recorded a nice bit of passage. At the peak there was c.150 hirundines and several Swifts, with birds moving through being replaced by new birds almost constantly and eventually less birds were hanging around.
A Hobby and a Peregrine went through north and Sparrowhawk, Buzzard, Kestrel and Red Kite were all seen today (six raptors in one day here is pretty good!). A Mistle Thrush flew over south east.
Colin noted the Willow/Marsh Tit pair in courtship behaviour and that it was probably a female Willow Tit and male Marsh Tit. Warblers seemed quiet in the cold conditions but there was a Garden Warbler in song near the entrance and a couple of Whitethroats around, including one nest building by the reservoir and another in song north of the railway.
He has also confirmed nesting of Long-tailed Tit (3 nests) and Greenfinch. Song Thrushes are definitely nesting on site somewhere and Starlings off site but nearby, as they are collecting food from around the reservoir and in the cattle field.
I had a Common Sandpiper at the Borrow Pit but there wasn't much more up there. On my way back down the reservoir I found our first Redstart of the year in the scrub along the western path. Later in the evening Mark had three Yellow Wagtails at the Borrow Pit too.
This is no Farmoor, Otmoor or Port Meadow. This is Grimsbury. It's Grim up north!
There is a running total year list in the link above.
Please send in your bird sightings to the B.O.S. and/or to me directly for inclusion on the blog. If you have some photos you would like to contribute please let me know (contact via the comments box on the right if you do not have my email already). Thank you.
