  1. I’m in a different part of #Cymru near #Corwen. There are cuckoos calling constantly here. I have heard cuckoos before, but never so frequently as here.

    1. Yellow-billed Blue-Magpie (Urocissa flavirostris)
    2. Common Cuckoo (Cuculus canorus)
    3. Eurasian Jay (Garrulus glandarius)
    4. Gray Bushchat (Saxicola ferreus)

  15. I heard a cuckoo, I haven’t heard one of those here for a while!

  16. First #cuckoo at 55°N, 4°W just now. I don't think this it particularly early and I know people further north have already reported them, but it's a data point.

    The #cuckoo has just arrived! And over a week earlier than usual (i.e. 25th April).

  22. Having red Nick Davies' book "Cuckoo: Cheating by Nature" [1], this paper is even more interesting:

    "Categorical identity signatures can reduce host error rates during brood parasitism", Dixit et al. 2026 journals.plos.org/plosbiology/

    "The African cuckoo finch Anomalospiza imberbis parasitizes several host species, each of which has evolved inter-individual variation in egg appearance (“egg signatures”) that facilitates recognition and rejection of mimetic cuckoo finch eggs. We demonstrate that egg signature traits in one host species, the zitting cisticola Cisticola juncidis, are categorically distributed. Field experiments reveal that zitting cisticolas make fewer Type II errors (accepting parasitic eggs) and Type I errors (rejecting their own eggs) than hosts exhibiting continuous variation. This challenges the long-standing expectation (from classification models, statistics, and signal detection theory) of a strict trade-off between these two error types."

  27. I didn’t immediately recognise this bird while it was flying around, but got a clear view when it settled on a dead tree - a Pallid #cuckoo. #WildOz #Birding #Tasmania #Nature #Birds

  28. A new bird! This channel-billed cuckoo was making a bit of noise, giving me plenty of time to get my camera. At first I thought the other other bird in the shot (the black one) was chasing it away, but I think it might be the cuckolded "parent", freaking out that its "baby" had fledged and left the nest.

  32. #Cuckoo left me #impressed.

    What an incredible #movie!
    At the start feels like pure #horror as it moves forward goes better into the #suspense category.

    I’m not going to make any #spoilers. This is one of those #movies that’s better to go completely #blind.
