16-10-2013 MORTAR COME!

Our four strong team headed out of the Fuglestation door before the sun had risen to open the nets full of anticipation for a big day at the nets.

With Redwings, Dunnocks, Robins and Song Thrushes calling from within the twilight it was clear we were going to have fun!

Sure enough the 1st net round was a busy one and the same pattern continued throughout regular net rounds until the threat of rain around 11.30 am put a holt to our standardised ringing session.

Nets were reopened in the early afternoon and the number of birds ringed by the end of the day reached 364 birds which is the busiest day we have had in the garden this autumn. These comprised of the following and must have resulted from the late afternoon arrival of birds on the 15th which made land fall as migratory conditions became unfavourable due to prolonged drizzle.

Sparrowhawk 1

Very Nisus Indeed! A 1K female Sparrowhawk at the smaller end of the spectrum. Note the very pale scapular frill. This is a very variable feature and tends to be a lot more common in juvenile males. Photo by Anders Nielsen

Before the nets were closed due to encroaching inclement weather the fuglestation was visited by a Group wishing to learn about birds and bird ringing. Hans and Gert arrived to take them through the process of what we do between the point in which the bird is caught and up to the point of  its release.

After the nets were furled we returned to Fuglestation to refuel and some of the team independeantly heard what sounded like another Nutcracker. Efforts to lure the bird in the high net were made again but must have fallen on deaf ears!

During the afternoon we all went seperate ways and went birding and  although many birds were observed the main talking point at the dinner table had to be the vast number of Wrens in around the Fuglestation with the low vegetation literally exploding with these underrated little birds!

Given that around 95% of the birds we have caught are 1K birds it would appear their arrival is just a sudden surge driven by post juvenile dispersal maybe resulting from a great breeding year. I guess only time will tell and  if the nets suddenly become festooned with adult birds then there is clearly something more behind this movement.

Crossbills are almost a daily event at Gedser in the autumn with birds streaming south at times. With this recent influx of Parrot Crossbills we have been taking advantage of the mixed flocks to learn the various vocalisations given by these birds in order to isolate the Parrots.With practice they do sound rather different and then its just a case of pin pointing the MORTARS in the flock. These three were part of a flock of around 9 birds seen feeding in a belt of coniferous trees just in Gedser town. Poor record shots by Jack Ashton-Booth

Male Parrot Crossbill record shot by Jack Ashton-Booth. Note how Mortar esq this bird real is with heavy front end (70%  of the body about the same depth and 30%  tapering quickly off towards the tail tip). Even at distance the head appears blunt and never acute but this is very subjective based on the angle in which the bird is observed.
