September Reveiw

The month was in general quiet, but dominated by a few very good species. The weather systems were almost all westerly, apart from an easterly on the 1st, and again on 17-18th. The month ended with a heatwave as a huge high pressure took hold across most of mainland Europe. Fed by southerly winds the temperature climbed upto 29 degrees C.
Highlight was the Barred Warbler found by John Archer on the 26th, the second record here. Also making their second ever appearance was a Curlew on the Ist and a Siskin heard flying over on the 27th. Lesser Redpolls were recorded on the 18th and 27th, the 3rd and 4th records.
Wildfowl numbers gradually increased, Teal reached 83 and Mallards 170. Apart from the Curlew and regular Common Sandpipers, max 6, there were no other waders recorded, which was disappointing. Raptors were just the normals (Peregrine, Kestrel and Sparrowhawk) with a presumed escape Saker Falcon seen on the 27th. The only Hirundines recorded were a group of over 20 Sand Martins on the 15th, part of a large movement of Hirundines across London at that time. Thirty Common Terns were recorded on the 25th, the largest count at the site this year. Numbers on Autumn passage usually reach well over 50. There were no unusual Gulls or Terns. The only Wheatear was on the 25th.
Warblers were also scarce with only Chiffchaff, Blackcap and Reed Warbler regular. A few Whitethroats were seen and a single Lesser Whitethroat, Willow Warbler and Garden Warbler failed to show. A couple of species that have been hard to find this year, Kingfisher and Great Spotted Woodpecker put in some welcome appearance's at EIDB towards the end of the month.
A little bit of visible migration took place with mainly Meadow Pipits and a few Finches, but the skies were mainly empty. So a strange month, at times devoid of birds, very low on migrants, watching the river was like watching paint dry but with some corking birds, very typical of EIDB and the area.
