I thought I would take a minor detour to check the field where we had
the geese yesterday and there they were so we would not need to waste time
locating them. I rang Larry who was nearly at Årnes, explained how to find me
and the geese and 15 minutes later he arrived. Larry’s hope was to download
data from “04” the bird with a yellow leg ring and which has a radio collar
rather than a GPS collar. The batteries on the radio collars last longer as
they do a lot less work than the GPS collars (which have all given up the
ghost) so the hope was to download 5 months worth of data (after a download in
October). Unfortunately despite being only 200-250m from the bird which should
have been close enough Larry could not make contact so it looks like this
battery has also packed up.
Counting the birds was as usual difficult due to
the high stubble and undulating terrain but we both counted 145 and this seemed
a good number so I began to doubt my 154 from yesterday. However I took
pictures over the whole flock whilst they were all standing alert and on the PC
counted exactly 154 birds!a presumed family group in flight. The bird in the middle is 7U. Note how the bird on the left has a seriously damged left wing. The result of gun shot? |
that damaged wing |
it must be difficult for this birds to fly the long distances required of it |
Larry and radio receiver |
the flock is on the field edge to the left of Larry |
here we see "04" which unfortunately didn't transmit any data |
Brilliant stuff Simon - really pleased you and Larry had the chance to meet up. Good to see photos of the state of the art tracking technology (plus broom handle and twig!!!) being deployed in Norway!!
ReplyDeleteThanks Brian. It was fun having Larry visiting and he is now the third international "guest" I and the geese have had after yourself and Thomas from Germany. Just a real shame the data didn't download.
