22/09 Redstart

We captured a Redstart on the 29-Aug-2017 at the Western Enclosure, Greenham Common.


It had been ringed elsewhere and it was a first year bird. We speculated it would be a pulli from a nest box scheme in the Northwest of the UK. We received details of the original ringing data this week. It had been ringed as a pulli on the 12-Jun-2017 at Locker Low Wood, near Hawnby, North Yorkshire, UK by Tees Ringing Group; one of a brood of seven

The map shows that we didn't get it quite right as the bird came from the Northeast in the North Yorkshire Moors Country Park. We don't capture many Redstart, only about 30 since the group started in 1967. This is a good record for us and gives an indication of where the Redstarts that pass through our area originate from.

Location: Greenham Common Western Enclosure
Session: 22-Sep-2017 07:40 to 11:00hrs
Headlines: On the way in kept meeting people who wanted to chat so started later than intended. As the last visit Chiffchaff dominated with Blackcap not far behind. Goldcrest numbers have also picked up this week; this is about on schedule for the beginning of the  autumn influx. A Reed Bunting that began calling towards the end of the session showed some interest when we responded with calls but eventually moved off..

Present: JL, IW, DL
Nets: 66metres in four rides of: 18M, 18M, 12M,18M up from 08:10 to 10:30hrs

Recaptures: None
Sightings 34 Species: Ian's list. A few Swallows and House Martins moving southeast for most of the morning. A high flying Magpie over is interesting and some rapture activity for a change. Dartford warblers were active today, and a few more Chaffinch about; these have been hard to find on the common until recently. At least four Song Thrush dropped in like migrants; the local birds being hard to detect this time of year. As we were loading up the car a Hobby gave prolonged close views and good aerobatics as it chased and captured dragonflies above us.

20/09 Greenham Common

Location: Greenham Common Western Enclosure
Session: 20-Sep-2017 07:30 to 11;00hrs
Headlines: After yesterday had good expectations for today. On arrival there was less bird activity though. Chiffchaffs were on the move and dominated the capture. Didn’t feel so tired today so stayed longer and managed to get a few more birds than I would have done. It got quite breezy so many birds bounced out of the billowing nets later in the session. I will give it a rest tomorrow as it is forecast to be much windier.
Weather: A bit breezier than yesterday, and more overcast, less sunny breaks
Present: JL, IW,RJC
Nets: 48metres in three rides of 18M, 18M, 12M up from 07:45 to 11:00hrs
Lure (audio): Blackcap Chiffchaff Goldcrest Firecrest Yellow-browed Warbler Willow Warbler Redstart intermittently.

Recaptures: 1 A Chiffchaff ringed 35 days ago (16-Aug) wonder where it has been until today?

Sightings 25 Species: Swallows on the move all through the morning and on a broad front. A scan east over the heath shown them to be skimming over the gorse and grassland heading in a southerly direction. Occasionally a group of House Martins drifted over at a more leisurely pace, heading in the same direction. A few more Greenfinch had joined the Goldfinch flock today and Meadow Pipit numbers are beginning to build. Surprisingly it was late morning before we detected any Magpie whereas Jays were having a noisy morning one or two flying high as they do this time of year. Some speculate that they are birds from the continent or further north in the move south for the winter. I think they are possibly youngsters that have been forced out by parents or more likely just moving about in search of the acorns. It would have been nice to capture the late Willow Warbler unfortunately it bounce out of the net before we could get to it. The Pied Wagtails were seen on the way off the common.

19/09 Greenham Common

Location: Greenham Common Western Enclosure
Session: 19-Sep-2017 08:00 to 10:20hrs
Headlines: First day allowed out after an enforced three week break (lung infection) Didn’t rush to meet the dawn. There was a lot of activity in the bushes around the enclosure when I arrived, it looks promising. A good capture of Blackcap and a few Chiffchaff. The Lesser Whitethroat was unexpected and late for this species. We had a good look at it to make sure it wasn’t Siberian! I think I may have missed some good birds since the beginning of the month though. It was good to get out and an enjoyable session, would have stayed longer but was very tired by 10:00hrs, took me all day to recover.
Weather: Sunny periods, calm
Present: JL, IW
Nets: 48metres in three rides of 18M, 18M, 12M up from 08:15 to 10:00hrs
Lure (audio): Blackcap Chiffchaff Goldcrest Firecrest Yellow-browed Warbler, Whitethroat Redstart intermittently.

Recaptures: No recaptures
Lesser Whitethroat 1st year
Sightings 25 Species: No hirundine today, lots of activity in the scrub mostly Blackcap  and the flock of Goldfinch, Didn't expect to see the Whitethroat or the Lesser Whitethroat. There was a tit flock moving north when I arrived, just to late to capture any of them. Pied Wagtails seen on the way off the common.

10/09 Thatcham Marsh LNR

Location: Thatcham Marsh LNR
Session: 10-Sep-2017 06:45 to 11:30hrs
Headlines: A good capture probably would have been more if the full reed bed ride nets had been erected. This year's visit is similar to the matching 2016 visit except the latter had more acrocephalus warblers; confirming that 2017 birds have left earlier than they did last year. Notes short as I couldn't make this session.
Weather: Breeze early, overcast later
Present: IW, DL, JHW
Nets: 138M; one  reed bed ride of 108M, two scrub rides of 18M and 12M up from 07: 15 to 11:00hrs
Lure (Audio): Blackcap, Chiffchaff, Goldcrest, Firecrest plus others
Capture (New/Recapture)
