Gulls in The Algarve October 2017

Steve asked about the gulls after my trip report to Portugal didn't mention any.

Portimao has a large fish harbour, which of course attracts many gulls throughout the year. The temperature during my trip regularly reached 35 degrees C +, so maybe this was the reason there were fewer gulls around than normal. It appeared that the Lesser Black-backed Gulls had not arrived in big numbers.

That said on my first visit I noticed an 3cy Azorean 'type' Gull peering down on me from the rooftop. This is my Azorean at the portico fish harbour, but so far no decision has been made on the previous two, so I will wait a while before documenting it fully. The light was very bright, so it was difficult to reproduce the correct grey tone of the upperparts.

Many of the Yellow-legged Gulls frequenting the harbour and the beach where we stay at Praia da Rocha are ssp. lusitanius. 1cy michahellis are more advanced in their moult having also moulted some coverts by October. Lusitanius 1cy can be told by the lack of covert moult and usually their small size. It is easier in January/February when the differences are more obvious.

Amongst the Lesser Black-backed Gulls that had arrived I recorded colour-ringed birds from England, France, The Netherlands, Norway, Scotland and Wales. There were also some that had been ringed in Portugal.

As well as the big gulls we did come across nine first-winter Slender-billed Gulls near Faro.

And of course a few Audouin's Gulls and some Med Gulls but these were shy this time around.
