Common Teal Anas crecca



Taxonomy

Taxonomic note
Common Teal A. crecca (del Hoyo et al. 2014) has been split into Common Teal A. crecca and Green-winged Teal Anas carolinensis (Handbook of the Birds of the World and BirdLife International 2020).
  
This change follows a revision to the scoring of the males' vertical white breast-side line, due to its role as a signal in display. As such the revised scoring is as follows: male A. carolinensis differs from A. crecca male in its vertical white breast-side line, replicated on rear flank (3), lack of white horizontal scapular stripe (2), and lack of narrow buff supercilium (above broad green “eyestripe”) (1); various other very minor differences cannot be scored (plumage characters capped at three), differences in measurements do not exist, behavioural differences are matters of frequency rather than type, and genetic evidence, while suggesting paraphyly involving A. flavirostris, indicates that hybridization is relatively widespread in Beringia (allow 1 for broad hybrid zone), indicating that carolinensis does warrant species status. 

Aleutian race nimia remains treated as a synonym of a monotyic A. crecca.

Population justification: The global population is estimated at c. 2,800,000 mature individuals (per Partners in Flight 2019, Wetlands International 2020). The European population is estimated at 557,000-915,000 pairs, which equates to 1,110,000-1,830,000 mature individuals (BirdLife International 2015).

Trend justification: The overall population trend is uncertain, as some populations are decreasing, while others are stable, increasing or have unknown trends (Wetlands International 2020). In Europe the population size trend is unknown (BirdLife International 2015).
