20-1-2021 EL PALMAR, ALBUFERA - BLUETHROAT (MALE) (Luscinia svecica)

The bluethroat (Luscinia svecica) is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. It, and similar small European species, are often called chats.
It is a migratory insectivorous species breeding in wet birch wood or bushy swamp in Europe and across the Palearctic with a foothold in western Alaska. It nests in tussocks or low in dense bushes. It winters in the Iberian Peninsular, the northern half of Africa, and in southern Asia (among others including the Indian subcontinent).
The bluethroat bird is similar in size to the European robin at 13–14 cm. It is plain brown above except for the distinctive black tail with red side patches. It has a strong white supercilium. Despite the distinctive appearance of the males, recent genetic studies show only limited variation between the forms, and confirm that this is a single species. Moults begins in July after breeding and are completed in 40–45 days, before the birds migrate.

The male has a varied and very imitative song. Its call is a typical chat chack noise.
Females of all subspecies usually have just a blackish crescent on an otherwise cream throat and breast. Newly fledged juveniles are freckled and spotted dark brown above.
The genus name Luscinia is Latin for the common nightingale. The specific epithet svecica is from Neo-Latin Suecicus meaning "Swedish". The colours of the male's breast were thought to evoke the Swedish flag, the yellow in the flag being more orange hued.
20-1-2021 MARJAL DE INTERIORES, ALBUFERA - EURASIAN KESTREL (Falco tinnunculus)

The common kestrel (Falco tinnunculus) is a bird of prey species belonging to the kestrel group of the falcon family Falconidae. It is also known as the European kestrel, Eurasian kestrel, or Old World kestrel. In the United Kingdom, where no other kestrel species commonly occurs, it is generally just called "kestrel".
This species occurs over a large range. It is widespread in Europe, Asia, and Africa, as well as occasionally reaching the east coast of North America. It has colonized a few oceanic islands, but vagrant individuals are generally rare; in the whole of Micronesia for example, the species was only recorded twice each on Guam and Saipan in the Marianas.
