Stow on the Wold - 30th December 2016, Blue Rock Thrush

Another bird that we really ought to have gone for sooner, only a short distance away in the greater scheme of things, a species that we'd not seen in the UK but have seen on numerous occasions abroad.

The visibility was very poor, but we made several circuits of the streets searching for the bird on a roof or chimney pot. Eventually it was turned up, in a back garden, by another birder who also searched proactively rather than stand waiting with the crowd.

The first sighting of the day was much later than the last couple of days and had it not been found then, we would probably have given up in the foggy conditions.

Truss's Island - 20th December 2016

This morning we met up with Mike Reed to catch and ring Mute Swan at Truss's Island. Usually we're relatively certain of how a session like this will progress, but this time it was a little different - and I'm not talking about the pigeon with the unusual neck attire.

As usual, birds were fed on the ramp until we could get them into a position where catching was possible.

Enticing swans into reach.

Metal and Darvic rings are fitted.

The alpha numeric codes are easily read, whether birds are on land or in the water.

Processed birds continue to feed once released back to the river.

Then, just as the captures were slowing down, a car drove up with eight cygnets in the back. Our session just happened to coincide with their release from Swan Support. They had already been ringed at the centre, but we were able to add Darvic rings, vastly increasing the chance of sighting reports.

The additional eight youngsters had Darvics added, then made their way down to the water and the assembled flock.

There were some opportunities to engage members of the public and quite a few people took an interest in our activities and reacted positively to the information that we were able to share with them.

We did try to ring the pair at Stanwell but both were much more wary than usual, prompting us to think that a past problem of people going on site to shoot at wildlife may have returned.

Total:  

Mute Swan - 12 (16)

28 Darvics applied to 12 new birds, 8 pre-ringed birds captured and 8 pre-ringed birds prior to release.

Other observed birds included black on white T3Z, L3O & L3N , and birds already in Mike's study 4DAZ, 4DAD, 4DAJ, 4DAG, 4DAR, 4CIW, 4DAH, 4DAT, 4DAF, 4DAU, 4DBE, 4DAQ, 4DBE and 4DAQ - all black on orange. Metal ring W28390 was also read in the field.

Wraysbury C6 - 18th &19th December 2016

18 December

Again it was another foggy day and with Chris, Lara and Waheed still slightly lagging after yesterdays run over to Pitsea, with few birds around, and also what was present were moving around little, we decided to wrap up at 10.30am with just four birds processed.

19 December

So having been at C4 on the previous day and done really poorly with just 4 birds ringed, we had seen large flocks of finches and thrushes on our way out so returned to C6 to try our luck.

Of course, things are never the same the next day and the very large flocks just didn't materialise. We did catch some birds however, and did a little better than the previous day.

Pitsea, North Thames Gull Group - 17th December 2016

This weekend was the first outing for Lara and Waheed to the tip at Pitsea tip to gain experience with larger species and gull ringing with the North Thames Gull Group. Unfortunately it was a foggy day, so the scenic views of the tip were rather limited, and alas so was the ability to Gull watch and look for colour rings. But, neither did it reduce the ability of the smell to get into everything! It is getting increasingly difficult to get food waste brought to any tip in the UK these days, and sometimes there is a longish wait before the first dust cart with any arrives with anything that will draw the gulls in. Fortunately today we did not have to wait long, but the Gulls that came in for the first catch were mostly Black-headed Gulls. We then had a fairly lengthy wait for the second catch, as the Gulls seemed reluctant to come in and feed, despite the compactors going over it several times, they seemed not to respond, but eventually they did, and we ended up with a bigger catch, with more larger birds this time, though just restricted to Herring Gulls. The bonus was a single adult Mediterranean Gull and an interesting Glaucous x Herring hybrid.

A majority of the Gulls were colour ringed increasing the prospect of later re-sightings. We also had a good run of re-traps/controls on the day, with 27, including a Herring Gull originally ringed on 29 June 1995 on the Isle of May -  21 years ago, and a Black-headed Gull ringed at Godmanchester, Cambs on 9 December 1989 - 27 years ago.

Broadwater GP - 16th December 2016

This visit would probably be the last of the year and we were on site with nets up before the Redwings began to move about. In addition, the new feeders have been up for a few days and all the food was gone when we arrived

We had  three nets in the area where Redwings roost and one of the ten nets was placed close to the remaining feeder. We also had the usual run of nets along the track.

As we've come to expect from this site, most of the Redwings did not fly about much before leaving the site, but we did catch a few. There seemed to be little else about other that a few tits and the feeders must have been emptied by squirrels since the area really didn't attract any birds all morning.

Beeley, Peak District, Dusky Thrush - 11th December 2016

Another early start, this time in order to head off towards Beeley where the Dusky Thrush has been quite reliable. The drive up was tortuous, particularly a very long section of roadworks with a reduced speed limit. It was after 11am by the time we were eventually there and failed to get a decent look at the bird that departed its usual patch of Hawthorn just after we arrived. We staked our claim to a spot on the mud, close to the dry stone wall that encompassed the small orchard where the thrush has been seen. There were plenty of people that had already seen it, but in the gloomy light some wanted better photographs, a video (the hope of one particularly optimistic individual) or just a better view. As we waited there were several exclamations that the bird had been spied only to be later dismissed as a Redwing.

It was seen briefly, not by us, before it disappeared to eventually take flight from a Holly tree making a diagnostic call, very different to the Redwings present. So, we pinned our hopes on 2pm. It had been seen on the ground, on the previous day, in the rain at that time. 2pm came, and went. Still no bird. Some 20 or so minutes later, Chris called 'that's it' as a bird arrived across the wall opposite - and it was! The bird stayed in the Hawthorn, feeding then preening. It was partially hidden behind twigs, and didn't drop onto the ground while we watched - so only record shots was possible.

Broadwater GP - 10th December 2016

We haven't ringed at at this site for a while and were joined by MRB, WA and Margaret. We had a couple of nets up before the Redwings left the roost although few birds were caught early on.

Wraysbury GP -9th December 2016

Having worked this area a few times now, we've been wondering how responsive the Redwings might be, at the end of the day, when coming to roost. The birds feed over a wide area and in spite of the large numbers we rarely catch more than a few in any net over the course of a morning. Perhaps it might to possible to draw them into the nets as the light fails at the end of the day.

We set 5 nets in close proximity, put the audio lures on and waited. We saw several large flocks arriving, but they were not pulled in and we only got three Redwing, a Song Thrush and a couple of Robins in total. We probably won't try again but at least we now know it it's not worth doing. 

Wraysbury GP - 5th December 2016

We returned to Wraysbury on a frosty morning and put up a total of 9 nets. We caught quite a few more Redwing, three female Blackbirds including a a definite continental individual and several Robins, some of which showed signs that they may be about to move on. Z958037 was ringed on the 2nd weighing 19.9g and only three days later it increased to 22.7g with the fat score going from 2 up to 4.

Staines Moor - 3rd December 2016

Today we tried for thrushes in the corner of the moor adjacent to Stanwell. We have seen lots of birds in this area but due to the height of the bushes weren't sure how successful attempts to catch them might go. We put up three double nets and played audio-lures, but there were far fewer birds and the temperature had raised by a few degrees.

There were 11 captures - we'll give it one more try if we get a forecast for a windless, cold and frosty day.

Wraysbury GP - 2nd December 2016

After a couple of days with rather harsh frosts, we tried for thrushes amongst the berry bushes on C4.
There were a lot of birds first thing and it was clear that more birds roost there than remain to feed in the immediate area. We know that they also frequent the pony field, foraging on the ground, but with the ground quite hard they were more likely to turn to the berry crop rather than invertebrate food. As it happened there was no frost today, but the ground was still quite hard.

Our most numerous capture was Redwing.
