Winter treasure 17: Ravens

31/12/20 It’s not so easy as you might think to identify a buzzard-sized raven in flight simply by size, unless there happens to be a crow mobbing it. And then you have to be certain that is a crow rather than a jackdaw or rook.

It has taken me a few years of experience and research to become confident in my identification of ravens. The first time I saw them must have been on a primary school trip to the Tower of London. As far as I know, I never saw or heard one again until I started walking the Southwest Coast Path. Making slow progress over the steep Cornish cliffs, I was alerted to the presence of an unfamiliar bird by a cronk: a deeper, gentler, altogether more beautiful and friendly sound than the caw of a crow.

 
Its voice is distinctive, but its pitch can vary, and this confused me at first. Sometimes the cronk is unmistakably low and sonorous; sometimes it is higher and sounds more like a gentle version of a crow. This is still the most reliable method of identification, however, along with its tail – if you manage to get a look – which is diamond-shaped (usually described as wedge-shaped), in contrast to the crow’s fanned tail. It has taken me many sightings and hearings, both at home and in the surrounding countryside, to be sure – absolutely sure – that the visitors to my garden the day after the winter solstice were a pair of ravens.

Spring treasure 15: Dawn chorus

30/5/20 Yesterday I went on a walk with a friend, her first outing alone since lockdown. She asked me if I thought it was true there was more wildlife and more birdsong since lockdown, or whether we were simply noticing them more. I have heard many people say it, and seen many videos of wild animals wandering care-free down empty high streets, but the question of there being more wildlife, objectively speaking, needed logical consideration. It was probably a subject for the radio programme More or Less.

When she began describing the things she’d noticed, it was clear to me that most of it was just a matter of hearing birds where traffic noise would normally drown them out or encourage them to move elsewhere; or birds and other animals being happy in places they’d usually avoid. Fewer people, less traffic and less noise all mean that animals may be considering raising a family or looking for food where they never would have before. People have also slowed down, are spending more time at home and probably more time walking and cycling in their neighbourhood; therefore they are most likely seeing and hearing things that usually pass them by. But I don’t really see how there can be more wildlife already. Perhaps there will be at the end of the season, if nesting is more successful or more widespread this year. Perhaps some plants and animals that are sensitive to air quality will also benefit, though I can’t imagine the effects would be noticeable just yet.

Autumn treasure 13: Goldfinches

23/12/2018 It took me months to attract the first goldfinches to the garden with nyger seeds. When they did arrive, I would see one, and then have to wait several weeks to see the next one. Still, I was thrilled with the odd sighting, and wished I could tell my father they were here. Like kingfishers, they look too exotic for England; and also like kingfishers, it only takes a glimpse to know which bird you have seen.
