Whooper Swan passage

23rd March 2011 – dense fog through the morning then sunny W1
Grounded Migrants
The dense fog that persisted through much of the morning disappointingly produced very little in the way of grounded birds with 2 Robin and a Wheatear the only evidence of new arrivals.
Diurnal Migration
A trickle of Meadow Pipit and Pied Wagtail continued to move through in the morning gloom, however, as the fog lifted a group of 85 Whooper Swan headed north – this would appear to be the largest flock ever recorded over the island.
Miscellaneous
Two Raven and a Little Egret were again logged.
Moths
The moth traps attracted Red Sword-grass, Dark Sword-grass and Oak Beauty with the latter the second new species for the island so far this year.
