On mud near Ivy Dock were 200+ avocets, some feeding while others roosted in a group and there was also a flock of 300 golden plover on mudflats off the park.
A pair of red-breasted mergansers flew back into the river and landed near the Pyefleet, also a common seal in the Colne.
On the saltmarsh 2 rock pipits and 4 reed buntings were noted.
A snipe was on the grazing fields and 2 little egrets roosted at the park pond on Thursday.
A flock of 45 white-fronted geese flew south past the car park at the country park at the end of Thursday afternoon. Presumably the same flock seen two hours earlier flying south from Fingringhoe nature reserve by John Thorogood.
A badger was seen first thing in the morning in the daylight near the entrance to the park on Thursday by Sheila Rayner. Her daughter was pleased to see a red squirrel earlier in the week cross the East Mersea road near Church Lane.
