23-7-2020 VILLALONGA RESERVOIR, VALENCIA - EURASIAN REED WARBLER (Acrocephalus scirpaceus)
%2020.jpg)
The Common Reed Warbler, Acrocephalus scirpaceus, is a medium-sized warbler measuring approximately 13 cm in length with a wingspan ranging from 17 to 21 cm. It exhibits an unstreaked brown back with buff underparts. Both sexes are identical in appearance, which is typical for warblers. Juveniles can be distinguished by their richer buff underparts. The species is characterized by a flattened forehead and a robust, pointed bill.
When identifying the Common Reed Warbler, look for its brown, unstreaked back and buff underparts. The bird's supercilium is less pronounced than that of the larger Great Reed Warbler. In flight, observe the wing-span and listen for its distinctive song.
This species is almost exclusively found in reed beds, often with interspersed bushes, providing it with the necessary cover and nesting sites.
The Common Reed Warbler breeds across Europe into the temperate western Palaearctic and is migratory, wintering in sub-Saharan Africa. It is also a resident species in large parts of Africa.

Males typically arrive at breeding grounds a few weeks before females. The species is generally monogamous, with pairs raising up to two broods per season. It is known to be brood parasitized by the Common Cuckoo.
The song of the Common Reed Warbler is a distinctive slow, chattering "jit-jit-jit" with acrocephaline whistles and mimicry.
Nests are built by the female over water, often in reeds, and are deep cylindrical cups. Clutches usually contain three to five pale green eggs with olive or grey speckles. Both parents incubate the eggs, which hatch after 9-12 days. Fledglings leave the nest after 10-12 days but are fed by parents for an additional 10-14 days.

The Great Reed Warbler is similar in appearance but is larger and has a more pronounced supercilium.
The Common Reed Warbler is primarily insectivorous but may occasionally consume plant material such as berries.
The IUCN lists the Common Reed Warbler as Least Concern, indicating a stable population.

4-5-2017 CORDOBA, ANDALUCIA - EURASIAN BLACKBIRD (FEMALE) (Turdus merula)
The Common Blackbird, Turdus merula, is a true thrush and a familiar sight in gardens and woodlands. The male is distinguished by its all-black plumage, bright yellow eye-ring, and orange-yellow bill, which darkens slightly during winter. Females and juveniles are more demure in their attire, sporting mainly dark brown feathers.
Adult males are entirely black with the exception of the yellow eye-ring and bill. Females are sooty-brown with a duller bill, and juveniles resemble females but have pale spots on their upperparts. The very young may also exhibit a speckled breast.
The Common Blackbird thrives in a variety of habitats including woodlands with dense undergrowth, gardens, parks, and hedgerows. It shows a preference for deciduous trees and areas with thick vegetation.
This species is widespread across Europe, western Asia, and North Africa. It has also been introduced to Australia and New Zealand. Its range varies from resident populations in the milder regions to partially or fully migratory populations in areas with more severe winters.
The Common Blackbird is territorial, especially during breeding season, with males displaying distinctive threat behaviors to ward off rivals. Outside of breeding season, they can be more sociable, often forming small flocks. The species is known for its adaptability to urban environments, where it may overwinter more readily than in rural settings.
19-7-2020 BUFALI,, VALENCIA - CATALONIA WALL LIZARD (Podarcis liolepis)
Podarcis liolepis, the Columbretes wall lizard or Catalan wall lizard, is very similar to the other lizards in the genus Podarcis. This species was formerly described as a subspecies of the Iberian wall lizard, but has now been elevated to species status. These are slender lizards with long tails, narrow tapered heads and long thin toes, and stout legs. Colours are variable, although generally grey-brown. Often very subtle spots and stripes along the back and flanks can be seen and these can be more distinguished in the female. The underside is a much lighter cream or beige with sometimes a reddish tint. Adults grow 15–20 cm in length from the nose to tip of the tail. Body length can be a little as one third of the total body length, the tail making up the other two thirds.
Physical characteristics Size: Adults grow to about \(15-20\) cm long, with the tail making up two-thirds of the total length.Body shape: They are slender with a long tail, a narrow head, and long, thin toes.Color: Dorsal colors are typically grey-brown with varied patterns. Females tend to have more prominent longitudinal stripes, while males are often smaller. Some individuals also have ventral color variations, including yellow, orange/red, and white morphs.
Habitat and behavior Habitat: The species is adaptable and can be found in various environments, including rocky areas, shrubby vegetation, and even human settlements.Distribution: Its range extends from the Rhône Valley in France to the Sierra Nevada in Spain.
Activity: They are diurnal and active, often seen basking, foraging, and hiding in vegetation.Diet: They feed on small invertebrates and sometimes fruit.Reproduction: As an oviparous (egg-laying) species, females lay an average of 2.80 eggs per clutch in continental populations.
