Good to see signs of life on here. I'd given up posting as everyone seemed to be finished.
I haven't done any TTVs this year - my local 10km squares had all exceded their minimum 8 tetrads and with a new baby in January, I didn't feel able to take on any squares further afield. However, I was interested to see that my previous efforts (15 TTVs and 687 roving records), although modest compared to some of the undertakings described on this thread, still put me in the top 10% of atlas surveyors, so I'm not feeling too guilty!
I'm continuing to put in a few roving records. I have one 10km square where I have recorded grasshopper warbler in three different locations over two years. All the sightings were within 1km of each other (but all in different tetrads), but each one only counts as possible breeding (S/H) and I am the only person to have recorded grasshopper warbler in this square. I wonder if the atlas methodology allows the organisers to take account of multiple possible breeding records in the same square to upgrade them to probable?
Just to state the obvious, you can look up quite a lot of statistics on the Atlas website.
I've recorded 101 species in winter (66 on TTVs) and 122 in the breeding season (87 on TTvs). Obvious omissions are that I have hardly recorded any seabirds - all my TTvs have been inland and I haven't seen many coastal seabirds that others haven't already recorded.
My most frequently seen species on breeding TTVs have been
buzzard,
wren and
chaffinch (all seen on 13/15 TTVs).
Wren was my most frequently seen winter TTV species too (12). If I was still doing TTVs this year I suspect that I would hardly be recording any wrens as I know from other fieldwork that I am doing that hearing a wren is now sadly a notable occurrence in these parts after the last two winters.
My most frequently recorded 'roving' species have been
pink-footed goose in winter (12 records) and
sedge warbler in the breeding season (17 records). I usually check the species list for a 10km square before submitting a roving record, so this must reflect something about these species being missed by other fieldwork in these squares.
