    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...

    Hi everyone, I have been at "Praia do Dafundo" yesterday (28/02/2025), a small beach at the entrance of the Tagus estuary nearby Lisbon, where I photographed this gull. There were some adult lesser blacked-back gulls (Larus fuscus) in the beach as usual in this time of the year. The immature...

    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...

One is an entirely dark blackish-brown bird (first 4 photos) whereas the other is slightly paler on the underside of wings and has a white...

    Puffinus sp. (Portugal) - shearwater quiz

    Dear all, On August 14 2022 I photographed this shearwater from a beach (Praia Azul), located a few kilometres South of the Berlengas Islands on the West coast of Portugal. I am assuming it is a Puffinus species due to the flight behaviour and size observed in the field. The most obvious...

    Puffinus sp. (Portugal) - shearwater expert advice needed

    Hi everyone, This morning (15/08/2022) I took these pictures of a shearwater from a beach (Praia da Formosa), just a little South of the Berlenga islands in Portugal's West Atlantic coast. At the site I identified this shearwater as Puffinus puffinus, but later when looking at the photos (the...

    Yellow-legged gull - Sesimbra (Portugal)

    Hi everyone, I photographed this gull yesterday (04/08/2022) at the fishing port of Sesimbra (Portugal). This was one among hundreds of yellow-legged gulls and a few lesser black-backed gulls. What caught my attention was the presence of an orange stain on the beak and legs that were neither...

    Larus fuscus intermedius ? - Sesimbra (Portugal)

    Hi Alexander, Thanks a lot for your comprehensive comments and the literature suggestions. I will certainly look at these closely! As you said, the human eyes are far better in judging the true mantle color of gulls. From my perspective (i.e., "eyes"), the gull in the right was a YLG with a...

    Larus fuscus intermedius ? - Sesimbra (Portugal)

    Hi everyone, I was looking back at some photos that I took on January 2nd 2022 with my cell phone in Sesimbra, a small town on the west coast of Portugal, south of Lisbon. I assume that the gull with the darker back is Larus fuscus, and appears to have characteristics of Larus fuscus...

    ID seabird - Portugal (West Atlantic coast)

    Thanks a lot Alexander and Rafael for your comments on these birds. Given your opinions and available photos of Gavia species in eBIRD, I tend to favor the "Gavia immer" hypothesis, but I'm not entirely sure, so I'll leave these observations as Gavia sp. And yes, Rafael, you are absolutely...

    ID seabird - Portugal (West Atlantic coast)

    Hi everyone, I photographed these 2 birds on 02/20/2022 in Cabo Raso, the most western location in mainland Portugal on the Atlantic coast. The birds passed a few hundred meters from the coast, at moderate altitude, in the North>South direction. At the time it seemed to me to be juvenile P...

    Portugal, Lisbon district

    Hi everyone, Yesterday (May 9th) I took these photos at Cabo Raso near Lisbon, which is one of the most western places on the Portuguese coast. My question is about the bird that is on the right side of the photos, which I think could be Puffinus puffinus or Puffinus yelkouan. This bird looks...
