My first walk of the year took me down into the valley of the River Thame near Chearsley (http://tinyurl.com/29adszv). The temperature throughout the walk was 3°C with about 90% thin cloud cover and some weak winter sun.
The following were of note.
27 species were seen and/or heard and recorded in BirdTrack (http://www.bto.org/birdtrack/). The key sighting was a small but dispersed flock of Teal (Anas crecca). There were at least 4 individuals but, possibly, 2 or 3 additional birds. Teal have yet to be noted by me on the Thame during the breeding season; so, my assumption is that these were winter visitors to the valley.
Some fresh Mole (Talpa europaea) activity noted where the land appeared just above areas subject to recent flooding.
