Attenborough CES, Sunday 22 May

Not a lot to report from the CES visit to ANR on Sunday. The wind got stronger as the morning went on and when we heard a large tree crash to the ground I decided it would be safer not only the birds, but also for the ringers, if we cut the session a little short. It sounded like a large fire-cracker going off, branches snapping as it hit the ground.

Garden visitors

Slightly off topic, but these guys have been making an appearance in my garden lately, at around minight, to feed on peanuts.

Box checking, 20 May

 Kestrel clutch

 I thought only their mother would love them, but Ian seemed very taken by these baby Jackdaws too.

Linby Linnet nest

Here are some pictures of a Linnet nest I've been monitoring. I ringed the chicks on 15 May.

Attenborough CES, Sunday 15 May

The morning started bright with only a slight breeze and the first bird out of the nets was a Cetti's Warbler, so all seemed well. Unfortunately it did not last, the breeze strengthened, the skies clouded over and it started to rain. The rain eventually made us take the nets down early and we ended with 32 birds of which 22 were new. The usual mix of birds, the only surprise, other than the Cetti's was a Whitethroat. Thanks to Ian for the pics.

The only British passerine with 10 rather than 12 tail feathers.

Examples of baldness in birds like this Great Tit are not that uncommon and there are various possible causes including mite damage, fungal infections and nutritional deficiency.

Tawny Owl update

Looking at the incoming data so far, a few thoughts on the situation with Tawnys this year. There would seem to be quite a bit of variation across the county, with birds generally doing less well in the north perhaps due to deeper and more prolonged snow cover. Also, things have been a bit unpredictable with a few birds breeding in new locations and some dependable sites being vacant such as Flintham Woods.

Two birds of note are one retrapped that's at least 7 years old, it was ringed & filmed by BBC in 2007 at Hawton. Then a chick ringed at Hawton in 2007 was caught for second year at Long Bennington.

Barn Owl update

Over the last two days I've have been checking, with Duncan & Ian's help, some of the Barn Owl boxes to get a feel as to how they might be doing this year in south Nottinghamshire. We checked 11 boxes covering seven territories, and 6 were occupied by Barn Owls: four on completed clutches and two on small chicks. Average clutch size is 3 to 4. Based on last year, I would have expected five pairs, so overall it was quite encouraging with birds off to a quick start. Also there's apparently good survival of adults as four of the females were retraps and the other two had been ringed as pullus last year. Lastly, Duncan finally got to ring adult Barn Owl after having processed 9 of them!

 A retrap female near Cotham - she was in moult and on 4 small chicks.
Ringed as a 5 last year.

Jackdaw invasion!

A short film of a story that unfolded recently in a box Jim went to check recently...

And a picture of the star of the show. (No, not you Duncan...)

Goldfinch nest

Some pics of a Goldfinch nest I've been monitoring. Chicks were ringed on 6-5-11.

Osprey platform

I've been diversifying my nestbox-making into Osprey platforms! This spring I designed and made a platform to go up on one of the Notts Wildlife Trust's Trent valley reserves. The design is an amalgam of advice from Osprey ringers, research on the web at mainly north American sites and a very useful site visit with Tim Mackrill and colleagues at the Rutland Water Osprey Project. With eventual ringing etc in mind, I've offset the platform to allow safe access to the nest.

The thinking is that the Rutland birds will sooner or later start to spread out, and this is the first of what will be a string of boxes along the Trent river valley corridor in Notts & Derbyshire. The young males from there are apparently proving adept at attracting passing Scottish female Ospreys.

Recent recoveries & controls

In the latest batch are 4 Barn Owls including a 4 year old bird and one which moved 31km into Leicestershire. A couple of fairly local Blackbirds included a 2 year old bird. A Goldfinch was tracked within the group - ringed in the Meadows and trapped 15 days later in Clifton. Two Kestrel movements were from Shelford to Tollerton after 4 years and Ashford to Hassop in Derbs over 3 years. A Derbyshire Reed Bunting found its way to Bestwood, but overshadowing that was a Barton in Fabis bird that was caught 153km away in Swindon!

Attenborough CES, Sunday 1 May

On a morning more suited to flying kites than erecting mist nets we persevered and completed the first CES visit of the year. Some ride clearance was required so the big team we had out helped make the clearing and net erection as quick as possible. The first bird into the nets as we were setting them was a control Blackcap, so not a bad start and the Cetti's singing near the nets also helped raise spirits.

As the morning went on the wind got stronger, the sun brighter and the catches smaller but we ended with 36 birds, 25 of them new birds. The full breakdown (new/retrap): Bullfinch 3/1, Blackcap 4/2, Dunnock 0/3, Wren 3/1, Garden Warbler 3/1, Long-tailed Tit 1/1, Willow Tit 1/1, Treecreeper 2/1, Chiffchaff 2/0, Great Tit 2/0, Robin 1/0, Blackbird 3/0.

The Cetti's Warbler sang all morning moving from one side of the nets to the other but unfortunately managed to navigate under or over them each time!

Holme Pierrepont, Saturday 30 April

Glorious sunshine and not so glorious wind rather limited our catch today, although we used the time constructively to get most of the remaining poles and guys in place across the site.

Our total of 26 birds was certainly not unprecented for this time of year and in fact there is often a bit of a dip after the main wave of migrants has passed and before the first youngsters start to appear. However, what we lacked in numbers we made up for in variety with 14 apecies trapped. Break down as follows (new/retrap): Garden Warbler (0/1), Blackcap (1/0), Whitethroat (0/2), Sedge Warbler (1/1), Reed Warbler (1/4), Willow Warbler (1/1), Chiffchaff (0/2), Blue Tit (1/0), Chaffinch (0/1), Bullfinch (0/1), Song Thrush (0/3), Blackbird (1/0), Long-tailed Tit (0/1), Reed Bunting (2/1).

Also around were a pair of Gadwall looking saucy, a Cuckoo, several Common Terns and several Lesser Whitethroats. Although we only caught one, Garden Warblers seemed to be particularly noticeable and singing in many places.

More Hucknall pulli

Some more local pulli ringed today, a brood of 2 Wood Pigeons at Bestwood and a brood of 4 Dunnocks in Hucknall. The Dunnock originally had 5 eggs but 1 failed to hatch.

Box checking technique

After a couple of awkward climbs and boxes that were tricky to see into, I decided to reach up and poke my phone through the hole to help me check the contents. The following two pictures were the result of this useful technique - not great quality, but quick, easy and cuts down disturbance when birds are incubating as in the first pic.
