It
has been more than a month since Charlie arrived at its nesting area on 3rd
June. We can now observe changes in Charlie’s activity pattern as time
enters July, which would appear to demonstrate that its young have hatched.
In
June, we can see Charlie mainly moved around the nesting area, with occasional
travelling of 3-8km away from the nesting site. It is known that both male and
female Grey Plovers share the duty of incubation. So these movements away from
the nesting area were presumably Charlie taking a break to feed, and may
also help to distract predators away from the nest.
The maps and traces below show the movement of Charlie
around the nesting area (shaded white) in June.
Day 1-7: 3rd-9th June |
Day 8-14: 10th-16th June |
Day 15-21: 17th -23rd June |
Day 22-28: 24th -30th June |
As
time enters July, we started to see obvious changes in Charlie's pattern of movement . Rather than using the nesting area as the “centre of movement”,
Charlie seems to spend most of its time at the northern shore of the two lakes 2km
to the north of its nesting area. It looks as though Charlie has hatched some young
and has now moved them a little away from the nesting area to feed.
This last map and trace show Charlie's movement away from the nesting area (shaded white) in July
Day 29-35: 1st – 7th July |
We
will now wait and see how long Charlie will stay with its young and in a couple
of weeks time, we hope Charlie will start showing us its southward migration!
