Since I don’t see many reports of sightings at Riverside Country Park, here's a brief report and some photos from the two visits I’ve made this autumn.

The first time I went was in the morning when the tide was completely out and you can see only, rather artistic looking, mudflats, with distant bird specs (this was about 3 hours before high tide):

At that time of the day the sun is in front of you and the waders are pretty far out. I don’t have a scope, so could only note: curlew; oystercatcher; brent goose; wigeon; teal; black-headed gull; black-tailed godwit; herring gull.  The blackheaded geese were some distance away so pics not very clear; the teal were hiding in the reeds...

 It's great for photographers too; there are rusting boats:

And roosting birds (the first two are turnstone):
