Brent return?

Three pale-bellied Brent today, following the same routine as last winter's birds.
On Red Nab an hour before high tide (9.2m). They fed on the plentiful gut weed until finally displaced 15 minutes before high water. Then flew to Ocean Edge salt marsh and continued feeding on the sparser gut weed there.
If they are last years birds, then a repeat performance tomorrow could be expected, although the slightly lower tide (9.1m) might exclude the salt marsh.

Both the above images are from Red Nab, the green gut weed can be seen on the rocks, but the Brent prefer to eat it when it is floating underwater.
The image below is on the salt marsh. The gut weed here grows on the mud between the sea grass. (MD)
