    Hi everyone, I have been at "Praia do Dafundo" today (03/10/2025), a small beach at the entrance of the Tagus estuary nearby Lisbon (Portugal), where I have observed and photographed several gull species. Among these, I am not sure about the birds species in the attached photos: The first and...

    Warbler - Lisbon district (Portugal), September 1st 2024

    Good evening everyone, I photographed this bird at a birdwatching hotspot called "Salinas de Alverca" a few months ago (September 1st 2024), which is an ex-salt flat region close to Lisbon (Portugal) and next to the Tagus river. The bird was fluttering through the vegetation next to a water...

    Small gull - (Lisbon, Portugal, 02/09/2025)

    Thank you very much for your comments and clarifications. In fact, the bird appeared to be shrunken as it bobbed in the water, which made it appear more compact than normal is.

    Small gull - (Lisbon, Portugal, 02/09/2025)

    Good evening everyone, I ask for help in identifying this gull that I photographed yesterday (02/09/2025) at beach "Praia do Dafundo" (Municipality of Oeiras, adjacent to Lisbon, Portugal). I went to this location in an attempt to photograph a Bonaparte's gull (Chroicocephalus philadelphia)...

    Sandpiper - Lisbon District, west coast of Portugal (January 26th 2025)

    Hi everyone, I photographed today (January 26th 2025) a sandpiper on the west coast of Portugal near Lisbon. The bird was resting on some rocks by the sea along with 2 sanderlings Calidris alba. It caught my attention because it had a grey-brown back, not as grey as the C. alba (in the photos...

    Wader - Lisbon District, Portugal (11/01/2025)

    Thank you all for your clarifying comments. Indeed, the difference in size and bill length between the two birds caused me some difficulty in the identification. I am now aware of the intraspecies variation among dunlins.

    Anthus sp. - Atlantic coast, Portugal (18/01/2025)

    Hi everyone, This observation was made in a flooded meadow near the Atlantic coast of Portugal south of Peniche. I am uncertain about the species of this bird. It had dull colors and a uniform brown overall appearance on the upper parts. It had slightly diffuse dark brownish stripes...

    Wader - Lisbon District, Portugal (11/01/2025)

    Hi everyone, I´m sharing a couple of photos of waders I took last weekend at the EVOA birdwatching site near Lisbon, Portugal. I have no doubts about the grey plover. However, the second largest bird (right in the first photo and left on the second) I´m not so sure. It looks like a dunlin, but...

    Seagull at Cabo Raso (Atlantic coast of Portugal), 26/11/2022

    Hi Lou, thank you very much for your comments. I certainly wasn't expecting that species! I have 2 more photos, but I don't think they help much with identification. What do you think? Thanks a lot! Luís

    Good evening everyone, On 26/11/2022 I photographed this seagull in Cabo Raso (Atlantic coast of Portugal) in flight to the North along the coast. Of a total of about 300 L. michahellis and L. fuscus that I counted in flight to the South during the morning, this was one of the rare gulls that...
