On 12 October 2020 , 10:25 hours, news broke into one of the WhatsApp channels broadcasting rare bird observations in Catalunya: ‘Cat Twitch’. Vittorio Pedrocchi asked for a BOC photo he had received depicting a shocking (bit burnt image of an) Azure tit (Cyanistes cyanus).

Soon later, it was learnt that Alfons Hernández had found it and photographed it at Bassa de Can Dunyó , at Lliçà de Munt, Vallès Oriental, Barcelona. The bird had been seen lingering around the reed beds, trees and the nearby stream, apparently behaving normal.

A number of local birders from the comarca (a country like division we have in Catalunya) had departed to attempt relocating this dream bird.

However, despite the available image depicted a non-suspicious pure individual, many doubts immediately arose within the group and beyond. Namely, the paucity of records elsewhere in Europe away from Finland and Poland. Birdguides website states that a German record in 1821 was considered an escapee and a bird in France in 1907/08 was thought to be a fraud or perhaps a hybrid. A further 2006 record in Germany was also placed in E category.

Besides, some members said the species had been bred in captivity near Barcelona.

By 14:58 sad but expected news came in: the bird was ringed (ring visible in the above photo). One minute later the ring was confirmed being plastic (black, with letters) and without any metal additional ring. The black ring was the code used by captive bird breeders in 2020, so the bird had to be a first winter individual escaped from somewhere. 

According to European Colour-ring birding website only 24 Azure tits had been ringed in Belarus in 2019 with a combination of two colour rings in one leg and a metallic one in the other, not this case.

Lawicki(2012) summarized the status and occurrence of Azure Tits and hybrids with caeruleus in Europe (Dutch Birding 34: 219-231).  He states that ‘Apart from the presumed escape in Germany, no other Azure Tits originating from captivity are known for Europe. The  species  is  rare  (although not unknown) in captivity, at least in the Netherlands ‘, therefore this record demonstrates its existence in captivity in S Europe and the possibility of producing observations such as this.

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
