I have a few birds which I haven't yet seen on Essex and wondered of any of you can point me in right direction?
1) Jay
2) Bullfinch
3) Gray and yellow wagtail
4) Mistle thrush
5) nuthatch
6) glucose Gull.
Well in Chelmsford
Bullfinches can sometimes be seen around the Chelmer Valley nature reserve in town, or at the Marconi Ponds reserve near Central Park, or out around the Baddow Meads.
Grey Wagtails seem to be regular summer visitors, I've seen breeding pairs (and young) in the past at the Essex Record Office sluice, the lake in Central Park and at the Chelmer Valley reserve and individuals along the river through the Baddow Meads.
Yellow Wagtails I saw quite a few out near Little Baddow on the Graces Walk track leading from the river Chelmer to Great Graces (it's marked on the OS 1:25000 map and google maps), usually around Hammonds Road.
Jay is one I find only occasionally on my wanders around Chelmsford, whether through bad luck or going to the wrong places I don't know, but have seen them in many parts of the local area so a case of keeping your eyes open.
Mistle Thrushes can be found in Central Park at times and I've been seeing 2/3 out on the large paddocks on the north side of the river Chelmer east of the Baddow Meads - go past Barnes Mill, past the first set of paddocks and the cottage garden and then to the large paddock in a rough meadow. Have seen them there quite a lot recently, along with lots of Pied Wagtails and Meadow Pipits.
Can't really help with the last two though, Nuthatch has eluded me in the local area and have never seen a Glaucous gull, but then I wouldn't recognise one if I did!
