A couple of weekends Toni Polo told the forum the amazing number of crossbills (Loxia curvirostra) that girdled the Sierra de Gúdar (115 in total). If you actually surprised how much and I seemed insurmountable, do not know how wrong you are ...
This weekend there were three people ( Juan, Edu and Maju ) of Horus Group Banding (of Madrid ) to share a few days of banding with us, Llebeig Group. His goal was crossbill, as they are doing a study on the species. The favorable results obtained in Gúdar with the species it was decided to repeat the place Saturday and Sunday (ie today) change in the banding area and saw Javalambre . So, Saturday at 7 am we were opening up networks in Gúdar both locals and Toni Polo, Tony Perez, Sam Garrett, Monica Escudero and me.
In the first round of review we found that networks would not be a normal morning, the networks were full of birds, mainly crossbills, but also greenfinch serrano (Serinus citrinella), chaffinch (Fringilla coelebs), coal tit (Periparus ater) ... . When we had finished out just birds of a network had to go to the next to get to the birds as ay! crossbills were lined , turning them into beautiful tapestries of yellow feathers, green, orange, red ... So while the other rings would not stop going to other nets.
The thing was moving and there came a time when the number of birds has stabilized a bit. We could take a break around 10:00 or 10:30, breathe a little and make a small summary of what we had ... many crossbills and, a few greenfinches, tit (Lophophanes cristatus), thrush Mistle Thrush (Turdus viscivorus) ... . and as a species far more curious small Short-toed Treecreeper (Certhia brachydactyla) .
The next round was the one who brought it was the surprise of the day. Santi Perez Toni and I headed to a seemingly empty network (first shock), which differed only three birds. While we wonder why a black hat, big, try taking off from the bottom of the net. After a couple of flutters dropped surrendered to see that it is properly engaged. is a carrion crow (Corvus corone) of many that move the area. No doubt the cause of the decline of catches in the network during the round.
After banding the corvid (first capture of this species for the group, by the way), we made a couple of passes over the networks (for which, of course, fell mainly crossbills) and we went to eat So I think we had won. Tired but happy we finished the journey. Summary
saw banding Gúdar (30-5-2009):
Short-toed Treecreeper (Certhia brachydactyla) 1 ex.
Coal Tit (Periparus ater) 12 ex. (1 recapture)
Crow (Corvus corone) 1 ex.
tit (Lophophanes cristatus) 2 ex.
Chaffinch (Fringilla coelebs) 6 ex.
common crossbill (Loxia curvirostra) 144 ex. (7 recaptures) Greenfinch
serrano (Serinus citrinella) 33 ex. (6 recaptures)
Thrush (Turdus viscivorus) 3 ex.
Total: 202 birds captured (188 banding)
Well, it seems to reach almost one hundred and fifty copies of banded crossbills was not enough, so today we went to try his luck in Javalambre . As the networks were already assembled the previous evening (By Toni and Madrid) this morning was just opened and had to wait for luck. Like yesterday, we were at 7 ( Toni, John, Tom, and I Maju) in those duties, and shortly thereafter we began to take stock of networks. The thing began unevenly. Only one of the three groups of crossbills picked networks, yes, a good number, while the other two fell mainly v erdecillos (Serinus Serinus), Linnet (Carduelis cannabina) and some chaffinch.
This pattern has remained more or less constant during the first two or three rounds, bringing little new and, as always, many crossbills. With the emergence of a Thrush one of the networks has begun the dance of species, encouraging a bit in the morning. The following new species that have appeared have been Bonelli 's Warbler (Phylloscopus Bonelli) , first one solo and slowly falling into cliques. They were accompanied by other species as a robins (Erithacus rubecula) players in the area. A nice player male Subalpine Warbler (Sylvia cantillans) ... and of course, all washed in crossbills (although all in the same group of networks, no trace of them elsewhere).
When we were more than happy to have reached the final round has brought, once again, a few surprises. A female Stonechat (Saxicola torquata) , a few more Bonelli 's Warbler, some Bunting (Emberiza cia) who had not deigned to appear on all morning (late risers are) and, of course, the star of the day, a beautiful jay (Garrulus glandarius) adult who has finished the day round. A bird without a doubt impressive. After picking we went to eat and say goodbye to the people of Horus Group, with which We love to share time and hope to repeat soon.
Summary Javalambre Sierra (31/05/2009):
Jay (Garrulus glandarius) 1 ex.
Coal Tit (Periparus ater) 1 Ex.1
Subalpine Warbler (Sylvia cantillans) 1 ex.
Bunting (Emberiza cia) 7 ex.
Blackbird (Turdus merula) 2 ex.
Bonelli 's Warbler (Phylloscopus Bonelli) 6 ex.
Linnet (Carduelis cannabina) 17 ex.
Robin (Erithacus rubecula) 3 ex.
Chaffinch (Fringilla coelebs) 5 ex.
common crossbill (Loxia curvirostra) 54 ex. (6 recaptures)
Stonechat (Saxicola torquata) 1 ex.
Serin (Serinus Serinus) 22 ex. (1 recapture)
Thrush (Turdus viscivorus) 2 ex.
Total: 122 birds captured (115 banded)
In short, I think it was a weekend well spent and productive. With a total of 324 birds captured, of which 303 have been banded and recaptured 21 of 17 species. Stress is only the amounts of crossbills ringed during the weekend: 198 birds of which 13 have been recaptured.
The photos will come later, I have to see which ones are best to send them, but it wanted to send him and before I forget.
