Got up very early on Saturday morning with a target of Nightingale, but was not successful. This is now multiple years in a row where I have tried, unsuccessfully, to hear Nightingale sing in London.
Highlights were my first calling Cuckoo for the year, views of singing Garden Warbler (one of six warbler species) and seeing the very young Black-headed Gull chicks on the Tern rafts (along with Common Tern also on nests).
Fishers Green is a lovely part of the Lee Valley water and woodland complex. I walked all around the Electricity Sub-station and some of the adjacent water bodies. A general observation was the amount of Dogwood (Cornus sanguinea) present; it really was everywhere.
I had a few plant galls of interest including my first ‘Sputnik gall’ for the year on Rose caused by the wasp, Diplolepis nervosa; they really are fantastic galls.
I recorded my first Italian Alder (Alnus cordata) – a non-native tree with noticeably more pointed leaves than our native alder – and the galls on it caused by mites, Acalitus brevitarsus and, seemingly, the angle gall Aceria nalepai (although the underside was a little confusing). This latter find is of real interest as A. nalepai is not recognised as causing galls on this particular host and I may return to collect some specimens for further examination.
Other finds of note included:
