Deux articles qui traitent l’identification de Gobemouche de l’Atlas (Ficedula speculigera) et les espèces similaires: Gobemouche noir européen (F.h. hypoleuca) et ibérique (F.h. iberiae), Gobemouche à collier (F. albicollis) et les hybrides albicollis x hypoleuca
Two articles dealing with field identification of the Atlas Pied Flycatcher (Ficedula speculigera) and similar species.
The first article is about the variability of plumage and morphology of the Atlas Pied Flycatcher and the overlapping characters with the Iberian Pied Flycatcher (Ficedula h. iberiae) and other similar species: European Pied Flycatcher (Ficedula h. hypoleuca), Collared Flycatcher (Ficedula albicollis) and also hybrids albicollis x hypoleuca.

Capsule: Low clutch size (CS) in the Atlas Pied Flycatcher breeding in evergreen Mediterranean forest was compensated for by relatively high overall reproductive success.
Aims: To describe the breeding ecology of the Atlas Pied Flycatcher Ficedula speculigera in detail for the first time, in an old oak Quercus suber forest.
Methods: A total of 102 nests were monitored during 2010–2012. Breeding phenology, population density, clutch and brood sizes, egg biometrics, breeding losses and breeding success were accurately determined.
Results: The species arrived in the breeding area in late April. Population density was very high with 4.87 (±1.02) pairs/ha. Mean egg laying date (LD) was 19 May and CS averaged 4.92 eggs. Hatching and fledging success were 88.7% and 83.5%, respectively. The number of fledged young averaged 3.8 (±1.66) and decreased with LD (4.2 ± 1.45 chicks fledged per nest at the start of the season versus 2.8 ± 1.56 at the end).
Conclusion: Lower CS compared to Ficedula hypoleuca populations was compensated by relatively high fledging success, thereby ensuring overall reproductive success of this species. Moreover, the Atlas Pied Flycatchers seem to benefit from the lower seasonality in their food in the evergreen habitat.
