it's RSPB Birdwatch this weekend - see https://www.theguardian.com/environment/2019/jan/25/bye-bye-blackbird-rspbs-big-garden-birdwatch-marks-40-years
it would be very interesting to hear what people saw in different areas of the country - and abroad, if you have an hour to spare. We keep a tick list of birds seen in our garden, starting afresh from Jan. 1st, and are up to 23 species so far this year. It finished up at 34 in 2018. The trouble with the one-hour Birdwatch count is that, whilst all the 'regulars' will get recorded, the less common but sometimes seen species won't make an appearance. One of our rarer birds here is the wren, despite the article saying they're recovering. We only saw one last year, and this year we were delighted to see another skulking around in the border under the big window, from where we sit and watch them.
The instructions for Birdwatch say that birds flying over don't count, but the article says you can claim Red Kite if one is overhead, as often happens here, they're very common. For our own list, we count birds that are 'earthed' by perching in trees or bushes, or on the ground or visiting the pond, and we include any we can see in neighbours' gardens either side, on the grounds that birds don't observe boundaries. There was a bullfinch in a tree next door on New Year's Day, rare here. We also include birds in our 'airspace', i.e, flying overhead in the space immediately above the garden, but we have them in a separate list.
