Another moth first for the farmlands

Boxworm Moth Cydalima perspectalis - another first for the farmlands- two firsts in last two days. Surprisingly this was the only moth in the trap yesterday evening? 
The ringing group caught 25 birds this morning with Sedge and Reed Warbler, Chiffchaff, Whitethroat and Blackcap. Unfortunately despite the huge invasion of Yellow-browed Warblers across the country and despite our best efforts (video below) we failed to find one round here. Yellow-browed is one of the most obvious missing bird species to the local bird list. 

Strapped an i-pod and speaker to the front of the mountain bike and hit the tracks trawling trying to get a Yellow-browed to call back. It didn't work.... today. 

Direct Action Meeting


Went to a local Green Party meeting yesterday evening to listen to guest speaker Dr Rob Basto, one of the Heathrow 13 and life long climate activist holding three criminal conviction medals. It was brilliant. 

One of the most interesting parts of the presentation was a graph of campaign planning and the relationship between risk and involvement. I've added a bit too it and also added an impact side to the chart (pic above). 

Basically the point is that social and environmental change is a community effort and all different parts of that community are of equal importance. Focused individuals and small groups have the biggest impact on anything but of course they need the backing of the wider community to achieve the bulk number of people, required for democratic changes. The relationship between risk and involvement is inverse but involvement is essential for change. So like I say, basically the point is that all spectrum of social and environmental activism should be planning and forming strategies together.

New moth for the farmlands

 L-album Wainscot- a first for the farmlands. An immigrant which has increased greatly across the south of UK in last 15 years. 
 Another Dewick's Plusia
 Angle Shades- always great to see. The odd Silver-Y and Rush Veneer most evenings recently, both migrant species. 
 Male Stonechat- the first of the autumn today. Also the first Siskin. The Wigeon influx continues- Marcus counted 34 yesterday.
Lapwings and Teal on Ed's Pool (the small area of wetland on the southern lake) where water levels are being controlled more carefully to create areas for waders. 12 Snipe, 1 Green Sandpiper and 22 Lapwing in there today.

Migrants etc

Whinchat- two yesterday on the associate members walk. 
 Also the first Spotted Flycatcher of the year found by Tomos
 Autumn male Northern Wheatear - one of three yesterday.
 Chiffchaff- one of the 30+ around. Also Meadow Pipits moving through, Swallows and the odd Sand and House Martin, Hobby yesterday, a few Yellow Wagtails and the odd Whitethroat and Reed Warbler.
First-winter  'Yellow-legged Gull' (looks a bit Caspo like) 
 An influx of duck in last couple of day with 65 Shoveler (above), 24 Wigeon (below), 175 Teal and 30+ Gadwall 

 Gadwalls- interestingly they seemed to think it was spring and the males were trying to mate with a female

 Common Blue- butterfly numbers are down now
 Ivy is typically providing one of the main sources of nectar in this part of the year. A lot of the insects are concentrating on Mile Road bridge. Red Admiral.
 Speckled Wood
 Hornet Hoverfly 
 Ivy Bee
 Seven-spot Ladybird
 Common Carder Bee
Syrphus sp.

Honey Buzzard

 Honey Buzzard- at height over the North Lake hide. The long tail, bulging secondaries and cuckoo like head are easily seen in this silhouette 
 The pale primary window is just visible in these pics. Roger's pics (above on FB link) show more detail (and the benefits of 500mm 'bazooka' lens). The barred juvenile like tail is shown in Roger's pics. Also the structure of the bird points towards a juvenile- with adults being much less harrier like with more bulging secondaries and even more characteristic general impression. Also the apparent pointed tail feathers and the apparent lack of any moult limits suggest a juvenile bird.
 Another dodgy pic
 Typical flat glide, with wings held in a slight arch 
 The upperparts show a pale area on the base of the tail, white primary patches and some pale area on the coverts/ mid wing panel. 

Just to wind up the dippers, a Common Buzzard appeared in exactly the same place the Honey disappeared. The typical pale breast band, shorter tail, less protruding head and compactness of a Common Buzzard is obvious. 
The local Kestrel not wanting to be ignored today too

With news from ex-Beddington birder Andy Taylor that seabirds were moving up the Thames (Greats. Arctics and a Long-tailed Skua past Swalecliffe), an Arctic Skua west past Rainham and seabirds moving all along the East coast, we were on Seabird watch at the farmlands this morning. There hasn't been an Arctic Skua at the farmlands since 2002, so one is due soon and especially considering the run of recent seabirds, hopes were high.

As usual, despite all the weather watching, news monitoring, modelling and tactical birding going on, we ended up seeing something we weren't even looking for and certainly would not have predicted in a blustery and cold north west wind- a juvenile Honey Buzzard, moving with the wind towards the south east (Basically breaking all the 'rules'). 

Instead of moving the Swallows were feeding around the lake suggesting that passerine migration was on hold in the much cooler conditions. This was reflected in a lack of any major visible passerine migration- just a few Mipits. However on some patches in North London 100+ Swallow were reported moving north. These migration lines/streams are clearly localised occasionally. 

Still on seabird watch from the obs and no doubt another vigil from the hide tomorrow, so fingers crossed. A local mega week at the farmlands- Sabine's Gull, Avocet, Kittiwake, Sandwich Tern and now Honey Buzzard- hopefully a skua tomorrow. 

Interesting to re-read this post from 2014: HERE
And here's a few pics from a mystery raptor a week or two ago: Mystery raptor
