A series following the 72 British mini-seasons of Nature’s Calendar by Kiera Chapman, Lulah Ellender, Rowan Jaines and Rebecca Warren.
Dear Readers, it’s interesting to write this just as the RSPB Big Garden Birdwatch results for 2026 are in – the Blackbird (Turdus merula) is at number 5, the same spot that it held last year. And yet, I haven’t seen a Blackbird in the garden for several years, and there have been a number of warnings about their susceptibility to Usutu virus, which has now spread north as far as Scotland. Advice re trying to prevent our garden birds from catching it varies, but one is to make sure birdbaths are emptied and refilled every day – it appears that the mosquito that transmits the virus is also very fond of water butts, so keep those covered too! It doesn’t appear to like ponds very much, maybe because ponds are often full of predators that will munch them up.
In her piece in ‘Nature’s Calendar’, Rowan Jaines has an interesting observation on Blackbird song. Blackbirds appear to modify their songs in response to noise: they increase the frequency and/or volume of the song, and change its length and timing. In urban environments Blackbirds tend to make their communications shorter, simpler and louder. There are two components to their songs: the ‘motif’ and the ‘twitter’. A ‘twitter’ is high-frequency but low amplitude, while a motif is low-frequency, high amplitude and more melodic. In urban environments the Blackbirds appear to increase the frequency of the motifs, but to also increase the proportion of the ’emotive’ twitter. In other words, the lyrical tones noted by W.H Hudson in his book ‘Birds and Men’ from 1901 are changing in city birds to something more urgent and serious. Hudson was ruminating on something that engineer and music scholar George Grove mentioned – that the song of the Blackbird resembles human speech in its tones, spacing, and change of pace. And I think I can hear this too…have a listen to these recordings from the Wildsong website, which I’ve only just discovered, but will definitely be exploring. The author describes them as ‘the dark star of the garden’, and I’d have to agree. Cheer yourself up, and have a listen.
