BRAN05 Moves direct to Germany 13th March 2019
Early this morning our second satellite tracked Brent Goose moved across the North Sea and straight to Germany. Again leaving very early morning and taking a similar route to BRAN04 this bird did not stop until early morning on the island of Juist in Germany. Hourly datapoints showed the speed and timing of this movement as well as the distance. We will see if this bird stages here or makes a further jump in the next few days.
Brent Goose Satellite Tracking Update 21st February 2019
The Brent Goose Satellite tracking project is going well. However, one tracker has appeared to have stopped working BRAN03 last sent data back on 29th January and we were unsure what had happened.. However, we now know it is on the bird because David Low has observed the bird in the field matching the colour ring (Green CC) and the collar is still on the bird OK and it is feeding and behaving normally. The remaining four are sending back excellent data and we have now raised the number of data points each day to show some very intereting data on the specific feeding and roosting sites. Most birds have generally roosted on Bridge Marsh Island and feed on Blue House Farm. However, in the last few weeks the birds have split a little and a couple have now joined the South Woodham Ferris flock, some of which appear to now roost south of the river. Some of these birds are likely to start to migrate in the next few weeks and we wait in high hopes we can track the precise route, speed and timing of this as they move across to Holland. With this in mind we have raised the number of data points collected on a daily basis for the next few weeks to see if we can get a more accurate idea of these movements.
The maps below show the February movements for each bird:
BRAN01 - Colour Ring Green CD Metal Ring GV77655 - This bird took a sigle trip out the the coast and back which is interesting.
BRAN02 - Colour Ring Green CA Metal Ring GV77652
BRAN04 - Colour Ring Green DL Metal Ring GV77653
BRAN05 - Colour Ring Green CM Metal Ring GV77651
First few days of Brent Goose Tracking 11th Jan 2019
The first few days of tracking Brent Geese has been very interesting. In general all birds seem to be roosting on Bridgemarsh Island and grazing on the fields at Blue House Farm during the day. All five geese have spent the last three days grazing within a few yards of each other - that is quite fascinating and shows that group caught together have for at least three days stayed together. Most of them have also roosted overnight on Bridgemarsh Island in pretty much the same spots most nights which is also very interesting, although one roosted the other side of N Fambridge and in the creek by South Fambridge on one night.
David Low has been out in the field observing the birds and we have established that of the 14 birds we caught it consisted of five pairs (ten individuals) and 4 individual unpaired birds. This added value and information is quite remarkable and will give us some incredibly enhanced data. He has also observed all the neck collared birds all of which seem to be behaving normally and showing no issues with their collars. The photo below shows one bird preening and David's observations have been very encouraging along with the tracking data showing all birds appear to be behaving as normal with the rest of the flock.

Below are the maps for the first four days of tracking for each bird.
Fishers Green pulli ringed Black-headed Gull 2A76 seen in Spain
One of the pulli ringed at Fishers Green this year has just been sighted in Spain at San Lorenzo beach, Gijón, Asturias, Spain. This is the furthest one of the Fishers Green birds has gone and we thank Nacho Vega for sending in the sighting.
Brent Geese return to the UK
David Low has been out in the field searching hard for ringed Brent Geese and has come up trumps with three of the eighteen birds ringed in January re sighted. Green AA (Wakering Stairs) and AG (Leigh on Sea) were seen on 24th October and Green AY (Shoebury) on 26th October. AA was paired with a female and has a juvenile with the pair. David has also reported good numbers of Juveniles in the flock so we are hopefull that here will be good numbers of birds at Blue House Farm when we are ready to resume catching attempts.
