Observations On Some Behaviours Of Krüper’S Nuthatch (Sitta Krueperi), A Little-Known West Palaearctic Bird, Tamer Albayrak, Ali̇ Erdoğan

Turkish Journal of Zoology

Some intraspecific and interspecific behaviours in Krüper's Nuthatch (Sitta krueperi) populations were observed in Antalya province, southern Turkey. An account of their endemic distribution in Anatolia on the one hand, and the lack of sufficient data on the other, gave rise to the need for such a study. The breeding behaviour in the populations is observed, particularly in the BÜK (Lütfi Büyük Yıldırım research forest) and ELMALI Cedar research forests. The results are given in 2 parts as observed behaviours throughout a year and breeding period, which are mating, nesting, brooding, parental care and rearing and territorial behaviours.

Incomplete lineage sorting can genetically link populations long after they have diverged, and will exert a more powerful influence on larger populations. The effects of this stochastic process can easily be confounded with those of gene flow, potentially leading to inaccurate estimates of dispersal capabilities or erroneous designation of evolutionarily significant units (ESUs). We have used phylogenetic, population genetic, and coalescent methods to examine genetic structuring in large populations of a widely dispersing bat species and to test hypotheses concerning the influences of coalescent stochasticity vs. gene flow. The Mexican free-tailed bat, Tadarida brasiliensis mexicana, exhibits variation in both migra- …
