Bird notes from today
- An adult Mute Swan present for a while c.07:15. Was not ‘pressured’ in to leaving: but left anyway.
- Single Swifts seen over at 05:55 and 06:50.
- No idea where the corvids were this morning – none by 05:40. Just a scatter of Rooks later.
- Calling Willow Warbler was no doubt starting its migration to Africa.
- Pied Wagtails back on the ‘football’ field in some number – 34 counted at 06:55.

The visiting Mute Swan leaves. From the orange tone of the bill an adult.

Always have a surprised look on their faces. One of the three Grey Herons this morning leaves.

A perky Chiffchaff. From this angle the supercilium looks deceptively long and wide. However any Willow Warbler at this date would be much yellowier-looking and would not show such an obvious eye-ring. Against the light the leg colour is not helpful. I had the advantage that the bird was calling.

Micro-moths a long way up lamp-posts are a challenge for the camera (and me). Rather over-enlarged this at least shows the salient inverted ‘V’ and spots on the wing-edges. It rejoices in the name Dingy Dowd (Blastobasis adustella).

Another long-distance micro-moth. Likely a Bulrush Cosmet (Limnaecia phragmitella). Where do they get these names – well the ‘phragmitella’ [reeds] bit I can relate to.!

This a species of stretch spider – apposite name! Of the genus Tetragnatha and likely Tetragnatha extensa as the most common. As usual a hand lens or worse is required for positive ID. (up a lamp pole – I think not)
