Nuevas herramientas para la difusión de rarezas

Aunque la fotografía digital, y particularmente el digiscoping, son técnicas muy utilizadas para la difusión de citas de rarezas, en ocasiones las condiciones de luz no permiten obtener una 'foto fija' muy nítida, buena o suficientemente clara e indicativa de lo que se estaba observando. En esos casos, la función de grabación de videos que muchas cámaras digitales tienen permite obtener una secuencia dinámica que, por lo general, ofrece mejores resultados que una simple fotografía fija. Es cuestión de probarlo: sacar algunas fotos fijas o intentarlo y luego un video. Esos videos, sean en formato *.mov o *.avi según las cámaras se pueden luego colocar en lugares como Youtube. Pierden un poco de calidad pero se puede reconocer la especie y, desde luego, se pueden utilizar luego en blogs o páginas web.

Este es el caso de algunos videos colgados en el blog birdspain y también de la observación, interesante y novedosa, de un Falaropo Picofino Phalaropus lobatus en el estany de Ivars, Lleida, el 11.4.2008, del que Sergi Sales, el autor, obtuvo el siguiente video, colgado ya en Youtube.



Abstract: New tools to broadcast rarity observations. In case of poor light conditions, an alternative to digital images or digiscoping is attempting a videoscoping file, using the video function of our digital cameras. Results are often better than snapshots and can be broadcasted through Youtube and latter embedded in blogs or websites. The above video shows an example of a Red-necked Phalarope seen inland at Lleida's Ivars lagoon on 11 April 2008 (Sergi Sales).

Ancient Murrelet (Synthliboramphus antiquus ), 1st for Spain, 3rd for the Western Palearctic

Imagen
On 24 May 2023, Roland Bekkers, photographed an Ancient Murrelet ( Synthliboramphus antiquus) at the Odiel river mouth , an important wetland in the Huelva province, in the Atlantic coast of Andalucia, S Spain. At 20:22 the same day the news came out and were broadcasted within the Rarebirdspain group. Despite the rarity of the record, a number of local birders decided to give it a try on 25 May morning.  Local birders asked to respect local colonies of Little Terns Sternula albifrons and Collared Pratincoles Glareola pratincola remaining within marked paths in any attempt of twitching the murrelet.  On 25 May, at 10:37 AM the bird was relocated c.400m from the mouth of the Mazagón Marina (José Luís Anguita, Manuel Bárcenas, Juanjo Cirpriano, Alfonso Barragán), UTM 37.138718, -6.841995 . See photos below (José Luís Anguita) and videos (José Manuel Reyes). Some boats flushed the bird c. 2000 m from the initial place and a bit later it flew a further 3000 m to the W remaining near the pl

Grackles (Quiscalus) in the Iberian peninsula

Imagen
Quiscalus mexicanus , Mexico, 31.8.2007 © Ricard Gutiérrez Grackles (genus Quiscalus ) are birds from Icteridae family, typical of Neotropical region, but also present in the Holartic, including USA coast. Typical 'resort' birds known by many as those 'black' birds frequenting the tables of hotels in the Caribbean or Mexican coasts trying to steal food from customer's breakfast or lunch.  Not a typical long-distance migrant group, they are believed to be quite intelligent, in a rather Corvidae mood, so despite they cannot be considered as true vagrants to the Palearctic according to the uncapability of crossing by themselves the Atlantic, it is true that they (presumably) board on ships to do the crossing. And not only one species but, at least, two having been recorded in Gibraltar and mainland Spain.  E-listed in Europe due to the 'current rules', a review of the treatment of what A listing means regarding 'clever' birds such as Corvidae
