    Bannerman’s Shearwater and Matsudaira’s Storm-Petrel

    Two people break 10,000 species, and on the same day? Can it be?

    I would guess this is the same person breaking records in 2007. https://www.freelists.org/post/tn-bird/World-Record-in-South-America And if he was training as a doctor back then he has achieved a lot in 16 years per LinkedIn, whilst also finding the time to see so many birds...

    Pallid or Common Swift - Whitburn, Co Durham, 5th Nov 2023

    A selection of my photos of the Swift sp that was around Whitburn yesterday. The majority of the time it looked very dark, just occasionally did it appear browner. I am leaning slightly towards Common, but am far from certain.

    Maroon-belted Chat-Tyrant

    The photo in the Maroon-belted Chat-Tyrant species account is actually a Rufous-breasted Chat-Tyrant. I have attached a picture of a Maroon-belted. Also I have recently uploaded a few photos of species that are missing from Opus and will upload a few more soon.

    Finland birding trip - Help requested

    I did a trip with Barcelona Birding Point to Finland and Norway this year, compared to other operators the price was reasonable and we pretty much cleaned up. Highlights for me were Gyrfalcon, Steller's Eider, Hawk, Great Grey, Tengmalm's and Ural Owls. Trip Report
