Buff-bellied Pipit (Anthus rubescens), 1st for Spain

Imagen
On 27.9.2011, a Buff-bellied Pipit ( Anthus rubescens ) was found at Parque de Bens, Western A Coruña city, Galicia, in NW Spain (Cosme Damián Romai). The news spread through rarebirdspain yahoogroups where the author published three photos here , here and here . Soon the bird, one of the first transatlantic passerine vagrants recorded in mainland Spain caused expectation and was seen and photographed by other observers: Fernando Pereira's blog here or Pablo Gutiérrez blog here . The bird remained on 28.9.2011 (Daniel López Velasco, Nacho Castelao, Pablo Fernández García and Cosme Damián Romai; Ricardo Hevia and José Miguel Alonso later) whilst on 29.9.2011 some video footage was obtained and reproduced here (Jose R. Bugallo, David Díaz, David Martínez y David Calleja), courtesy of David Calleja. The Buff-bellied pipit is a rare vagrant to Europe from its American breeding grounds (see enclosed map from Avibase ). Interestingly, the day previous to the Galician arriva

Interspecific Vulture courtship? [¿Cortejo interespecífico entre buitres?]

Imagen
Javier Elorriaga, the ornithologist based on Tarifa and working for Fundación Migres studying mainly birds of prey has kindly provided us a video footage including two vulture species: Griffon Vulture (Gyps fulvus) and ... Rüppell's Vulture (Gyps rueppellii), a rarity in Spain. Besides the interest of having both vultures in the same frame, what is amazing is the behaviour of the 'pair'. Both birds seem to be conducting pre-mating behaviour. As explained by Javier: 'el Ruppel es de aproximadamente un año de edad, el fulvus creo que de 4 año calendario....entre fulvus es normal, pero siempre se ha interpretado como un síntoma de emparejamiento...lo que se ve en el video duró casi media hora y también incluia a los dos bichos cogiendo piedritas con el pico, etc...es la segunda vez que veo este comportamiento...en el informe que mandé al CR con fotos de Ruppel, hay una foto, en el mismo sitio,en la que se el mismo comportamiento....' [The Ruppell's is c.

Not all the sea is uniform: extreme pelagics produce extreme rarities [No todo el mar es uniforme. Las pelágicas extremas producen rarezas extremas]

It has been just known that on 10.9.2011 a Black-bellied Storm Petrel ( Fregetta tropica) has been seen at Banco de la Concepción area, c.40 nautic miles N of Lanzarote, Canary Islands. An intrepid bunch of birdwatchers coming from all over Spain leadered by the keen photographer and birdwatcher Juan Sagardía scored what was the 2nd record for the Western Palearctic and the 1st for Spain. Why going to that area and not to another? Why seawatching somewhere and not in another part of the 'rather uniform sea'? Main reason is because sea it's not uniform. That's it. A recent project carried out by a number of institutions and covering 10 sea areas in Spain, the Life Indemares , does focus in the importance of those areas not only for foraging vertebrates but for the whole ecological pyramid. It's not surprising that Banco de la Concepción is one of those areas. There is a detailed factsheet on the area here . Will the map above point out seabird hotspots too? It
