19/11 Greenham Common Feeder

Location: Greenham Common Estovers Feeder
Session: 19-Nov-2017 07:30 to 11:20hrs
Headlines: It was not as cold as forecast though it got colder later. We had a good variety of species but not as good as winter 16/17 for visit 02 of 10. This site has more  species visiting the feeder and in the surrounding scrub than the Bagnor and Snelmore Feeders. A comparison of Blue, Great and Coal Tits between the two periods shows Blue Tit number to be up this year due to differences in the number of 1st calendar year birds captured as for the other sites. For Great Tit the numbers are down this winter not sure why. Coal Tit numbers are up as they are at the other feeders. It is good to see a few more Goldfinches at the feeder but not in the numbers of a couple of winters ago yet. Not as many Greenfinch are coming to the feeder this week. Some Redwings are still responding to audio while others ignore it. The net where we were capturing these is near the cattle pens and a roundup later in the  morning meant they were put off while this took place. Towards the end of the session birds visiting the feeder stopped which is unusual as we often get a late flush here.
Weather: Cloudy early, clearing later, getting colder, calm
Present: JL, IW, JHW, DL, JPM
Nets: 72metres in six rides, 10m, 12m, 12m around feeders, 10m, 10m, 18m scrub nets.

17/11 Bagnor Feeder

Location: Bagnor Feeder Visit 02 of 10
Session: 17-Nov-2017 07:40 to 11:30hrs
Headlines: Another session showing the difference in totals between this winter and last winter and showing the lack of first calendar year birds in winter 16/17. A very busy session kept both of us ringing for the whole session. Some interesting pulli captures: the Great Tits that nested in Mount Hill box A03 seems to have been particularly successful with five of the ten pulli ringed  in May recaptured so far this winter. The box is about 2km away but much further for the birds that will have travelled along hedgerows and field margins. They probably roost in the copses and borders at Mount Hill. They may even still roost in their natal nest box, travelling out each day in search of food. They probably have regular circuit including the gardens of Bagnor village and other hamlets in the area, visiting our feeder as part of a regular route, returning each evening. Sometimes individuals usually attending this feeder turn up at the Snelsmore feeder the other side of the common near the car park entrance. A look at visit 02 totals for the last 10 years shows that winter 13/14 also had a low capture. A pleasant day once the sun came over the tree line.
Weather: Ground frost, cold calm, later warmer in the sun.
Present: JL, IW
Nets: 12metres one 6M net each side of feeder. Up from 08:00 to 11:00hrs
Lure (feeder): peanuts. black sunflower, fat balls
