Ceryle rudis syriaca Roselaar, 1995 was separated from nominaterudis only by its longer wings. As variations in the wing length ofCeryle rudis follow Bergmann's rule, it is suggested thatsyriaca is not recognised as a separate named taxon. Die Trennung vonCeryle rudis syriaca Roselaar, 1996 als eigene Subspezies basiert ausschließlich auf der etwas größeren Flügellänge. Da gezeigt werden konnte, daß die Flügellänge des Graufischers derBergmannschen Regel folgt, wird vorgeschlagen,syriaca wieder… 
Evolutionary Significance of Geographic Variation: Some Examples From Birds
Study of the geographic variation in birds usually focused on morphologic variation, and the insights from the morphologic variation were used to solve the taxonomic problems (Johnson and Marten
On the validity of Bergmann's rule
TLDR
The occurrence of Bergmann's rule in birds and mammals is reviewed, using only studies where statistical significance of the results was tested, to test whether sedentary birds conform to the rule more than migratory birds.
