"Seen from" possibilities!

Today was the last of the "isn't it a lovely day" greetings for about a week or so and we finished off the winter bird survey for SD45.  After yesterdays comment, what a surprise that TWO male Pochard were present today!  Malcolm also located a very mobile Chiffchaff on Middleton along with at least two Goldcrest but still no Cetti's.

Chough - seen at least twice
Pale-bellied Brent Goose - on the shore off the childrens play area, viewable from Knowlys road vantage point
Chiffchaff - one Middleton NR
Pochard - TWO drakes model boat pond
Med Gull - one ad harbour mouth
Red-throated Diver - one in second channel offshore
Eider - 520 - pretty accurate
GCGrebe - 2 

Also:
Chris Batty watched the Black-throated Diver leave Blea Tarn reservoir for FIVE MINUTES on the following trajectory at 1639hrs. It did not waver from the straight line flight during this period and, assuming it does not change direction when reaching the sea, suggests it is pitching in somewhere around the old Sandylands sewer outfall south of the Stone Jetty. There is a fairly wide channel here, even at low spring tide. Various vantage points suggest themselves for monitoring this flight eg watching the halfway stage from the raised south end of the golden ball tidal road and more coastally: end of Royds Avenue or even scoping north from Knowlys Road which would give good evening light as well as a 'seen from'!
