    Merlin ID

    I've picked a few tracks where it sounds like a 'bog standard' Iberian Chiffchaff to me, Andy, although that's no guarantee!

    Merlin ID

    On this current recording it's suggesting Wren.

    Merlin ID

    I'm sitting here on the edge of Southampton in the southern UK running the Merlin app (on android) for which I have the Western Palearctic pack installed. I'm playing a 'standard' Iberian Chiffchaff song from xeno canto and Merlin doesn't recognise it despite Iberian Chiffchaff being a species...

    Large insect Fuerteventura

    With the tubercle on the prosternum (top pic if you take the detail out of the shadows) and the very long wings it should be Cyrtacanthacridinae and with a lack of colour in the forewing (although it's a bit difficult to see which wings are showing) I'd have thought Schistocerca gregaria (Desert...

    Caspian, Yellow Legged and Herring Gulls

    In terms of length, wingspan and weight they are all roughly the same size. This article is quite interesting (well to me, anyway!) https://gull-research.org/cachinnans/polska/images01/June21CaspianGulls.pdf

    EOS RP with EF 100-400mm lens

    I found when using the EOS RP , the adapter and an EF 100mm macro that the focus point would often move off centre (bottom left quite often) even though I had set the touch screen off. As I don't do movies I programmed the Red movie button to set Centre Focus Point.

    Leica 8x32 HD vs papilio 6.5 or 8.5x21 For insects and butterflies?

    Hi Sam I'm not someone who is very good at analysing why I like a pair of binoculars but I'll try! For birdwatching what I particularly like about the Leica Trinovid HD 8x32 is (1) They are a decent weight (630g) so have a good solid feel in the hands without being overheavy - I struggle with...

    R7 for bird photography and birds in flight

    Pretty sure you've got a full range / 3m to infinity switch on the side of the barrel rather than a full range / 20m to infinity (latter is on my 800mm F11)

    Black-throated Diver age. Hampshire(UK),23.11.23

    I thought the Black-throated Diver in the attached images (taken in Southampton (UK) on 23.11.23 by a friend) was a juvenile/1st winter but it was suggested that it is an adult and I would be grateful of confirmation of age. Thanks in advance

    UK Dragonflies and Damselflies 2023

    I went to the Hampshire coast yesterday (17.11.23) No luck with any Vagrant Emperors or Green Darners but a couple of male Common Darters sunning themselves. There are no frosts in the local forecast in the next two weeks so there should still be some flying in December.

    Grasshopper ID - Holme Fen , Cambridgeshire, UK

    No - they're not present. The only two uk Chorthippus species with the angled pronotums are vagans and brunneus which can be separated by the position of the (principle) sulcus (males and females). I have usually to get a sound recording of male Chorthippus species when I'm in Spain to get it...
