Lesser Kestrel (Falco naumanni, Fleischer 1818) is one of the smallest European raptors (wing-span 58–72 cm, body mass 120–140 g).It is a trans-Saharan migratory falcon that overwinters in Sahel area (Limiñana et al. Most common in summer; breeds in buildings, old ruins and also cliffs. It has a roughly two-to-one range in size over subspecies and sex, varying in size from about the weight of a blue jay to a mourning dove.It also ranges to South America and is a well-established species that has evolved seventeen subspecies adapted to different environments and … ABSTRACT . This could help wild- life managers to evaluate the future effects of climate 153 . 2) Breeding success. The reasons for this decline are unclear, but reduced nest-site availability might be a major cause. Widely distributed throughout the region. 2012) and breeds colonially in cavity sites in old buildings or under roof tiles in western Europe (Negro and Hiraldo 1993).Lesser Kestrel is predominantly insectivorous, feeding mostly on … Lesser Kestrel Falco naumanni / Common Kestrel Falco tinnunculus. Adult male with clean, grey cheeks, no moustache-stripe and no streaking on crown. Lesser Kestrels laid their eggs between 24 May and 2 June each year.

In addition, the Decree 110/2015 of 19 th May, which regulates the European ecological network Natura 2000, provides specific measures for the conservation of steppe species and urban birds (both encapsulating lesser kestrels).

Lesser Kestrel - Falco naumanni small falcon,s breeds from the Mediterranean, Afghanistan and Central Asia, to China and Mongolia, summer migrant, wintering in Africa and Pakistan. We tracked individual lesser kestrels using GPS-dataloggers (GiPSy models 2, 4, and 5; weighing up to 2 g; Technosmart, Rome, Italy) with small-sized batteries (90–100 mA, 2.2 g). We found in lesser kestrel Falco naumanni nestlings that the GSH:GSSG ratio, which decreases with systemic oxidative stress, increased with the size of the colony where they were reared, but the expression in feather melanocytes of five genes involved in pheomelanin synthesis (Slc7a11, Slc45a2, CTNS, MC1R and AGRP) did not vary with colony size. Here, we use the Lesser Kestrel as an example for our data-based model because it is a particularly well-studied species. Partial post-juvenile moult confined to body, scapulars and, sometimes, lesser and median coverts; starts late August and finished in January. Lesser Kestrel (Falco naumanni) Photo no. 15621. Other habitats include orchards, holm and cork oak open woods and eucalyptus. Juvenile with flight feathers, greater coverts and primary coverts with broad pale tips; streaked breast; fresh plumage without moult limits on the wing. Both females and juveniles can be separated from Common Kestrel by head pattern and feather pattern to upperparts; head is plain except for dark moustache below the eye and pale cheek patch reaching the crown, no dark eye-line as in Common Kestrel; upperparts finely barred i.e. Identification of perched birds.

Notwithstanding the conditions laid down in Annex V of Regulation (EC) No 894/97, a minimum mesh size of 120 mm shall apply to greater spotted dogfish (Scyliorhinus stellaris) and a minimum mesh size of 90 mm shall apply to lesser spotted dogfish (Scyliorhinus caniculus) in all waters situated north of latitude 48°N, but excluding waters in ICES Divisions IIIb, IIIc and IIId Bare parts always pale/bright yellow compared to rich ochre in Lesser Kestrel.

Moreover, lifetime reproductive success of Lesser Kestrels was positively associated with colony size, and individuals can predict final colony size early in the breeding season, so assumptions of both hypotheses were fulfilled. During a 6-year study in Spain, we gathered information on 486 subsequent breeding attempts and on 26 explanatory variables which evaluated individual experience, conspecific cues in terms of breeding performance and colony Flight identification. AGEING In this case, though, it's much more likely to be Common Kestrel, as Lesser Kes is a summer migrant to Europe, spending its winters in sub-Saharan Africa. Circum-Mediterranean populations declined sharply during the 20th century and the species is categorized as Vulnerable on the IUCN Red List (BirdLife International, 2000; IUCN, 2003). A review in 1990 showed that the only large population outside Spain was in Turkey.
