Might well have missed:
Lesser Whitethroat - didn't hear myself but recording checks out - never heard in garden before either.
Garden Warbler - didn't hear myself but recording checks out - never heard in garden before either.
Overflying night birds - Moorhen, Coot, Water Rail - had no clue - have never heard myself.
Siskin - consistently detected not seen or heard personally from garden.
Snipe - detected but not seen or heard personally from garden.
Goldcrest and Firecrest - picked up daily - was not totally convinced as only 5-6 large conifers back of garden. I spent days and days looking and caught a glimpse of one of the other (was too quick to tell which) - so more convinced they are there I've just not seen.
Overflying waders, Dunlin, Avocet (good few times detected) etc
In the winter - Redwing - hadn't seen any - or heard any (but not been outside in garden for periods of time) - yet for a few months Redwing was in top 10 !
Missed first instances of
House Martin - it detected before we saw.
Swallow - it is detecting but despite looking not seen yet
