On February 16th, I and Luís Campina found an adult Lesser Flamingo (Phoenicopterus minor) in the Cerro do Bufo saltpans (Castro Marim). It was initially found at 10:30 a.m. on the South-eastern side of the saltpans and later on it was relocated in the West side at 13:30 p.m.
There are at the present date, four accepted records by the Portuguese Rarities Committee (Comité Português de Raridades – Sociedade Portuguesa para o Estudo das Aves):
- 1 adult, Vasa-Sacos, Tejo Estuary (Santarém), May 13th, 2000 (C. C. Moore in Costa et al. 2003);
- 1 adult, Samouco, Tejo Estuary (Setúbal), January 21st, 2001 (L. Gordinho and L. Reino in Costa et al. 2003);
- 1 adult, Ilha da Murraceira, Figueira da Foz (Coimbra), June 15th, 2005 (D. Rodrigues in Jara et al. 2007);
- 1 adult, Samouco saltpans, Tejo Estuary (Setúbal), December 2nd-13th, 2005 (A. Rocha in Jara et al. 2007).
Up to 2004 there were 12 accepted records for Spain, 11 for Continental Spain and 1 for the Canary Islands (De Juana 2006).

Pato-rabilongo Clangula hyemalis em Castro Marim
No dia 19 de Janeiro de 2008, eu e Luís Campina observamos uma fêmea em plumagem de Inverno de Pato-rabilongo (Clangula hyemalis) no Esteiro da Carrasqueira (concelhos de Castro Marim e Vila Real de Santo António).
Provavelmente será a mesma ave que foi observada a 23 de Dezembro de 2007 (Peter Dedicoat, June Taylor, Georg Schreier, Ray Tipper in Noticiário Ornitológico da SPEA).
Long-tailed Duck Clangula hyemalis in Castro Marim
On January 19th 2008, I and Luís Campina have recorded a winter plumage female Long-tailed Duck (Clangula hyemalis) in Esteiro da Carrasqueira (concelhos de Castro Marim e Vila Real de Santo António).
It probably is the same bird recorded on December 23rd 2007 (Peter Dedicoat, June Taylor, Georg Schreier, Ray Tipper in Noticiário Ornitológico da SPEA).
A ave em causa foi novamente observada no dia 26 de Janeiro.
The same bird was seen on January 26th
Seen again on February 16th.

Ganso-bravo-oriental Anser anser rubrirostris em Castro MarimNo dia 19 de Janeiro de 2008, eu e Luís Campina detectamos um bando de 20 Ganso-bravo (
Anser anser) numa zona alagadiça a sul das Aroucas, adjacente às salinas do Cerro do Bufo (Castro Marim). Uma das aves possuía o bico cor-de-rosa e mais compacto e pesado do que os restantes gansos. A ave em geral parecia ser ligeiramente maior e mais pesada do que a subespécie nominal e com o pescoço mais longo. A cabeça e pescoço eram duma coloração mais acinzentada do que os restantes gansos presentes. Em voo aparentava ser ligeiramente mais pálida nas partes inferiores.
A ave em causa apresentava características da subespécie oriental do Ganso-bravo,
Anser anser rubrirostris. No entanto, não será de descartar a possibilidade de tratar-se de uma híbrido entre
A. a. anser e
A. a. rubrirostris.
Eastern Greylag Goose Anser anser rubrirostris in Castro MarimOn January 19th 2008, I and Luís Campina have found a Greylag flock with 20 birds on a small wetland south of Aroucas bordering Cerro do Bufo saltpans (Castro Marim). One of the birds presented a pink bill, which was more compact and heavier than the others geese. The bird looked slightly bigger, heavier and with longer neck. The head and neck were greyer and in flight the under parts were a little paler.
The bird appears to belong to the Eastern race of Greylag,
Anser anser rubrirostris. But a hybrid between the two subspecies should be considered.[/FONT]
