Cinnamon Teal x Eurasian or Green-winged Teal

Cinnamon Teal x Eurasian or Green-winged Teal hybrid, Mittelriede, Braunschweig (Germany), late January 2010 - copyright Joern Lehmhus
(plate ID: 0724)


Apparently this bird disappeared after one day preventing Joern from getting a photo.  He tells us it was ringed with a mint-green plastic ring on one leg, so surely an escape.

Cinnamon Teal x Northern Shoveler

This is quite an uncommon hybrid.  Steve highlights the Cinnamon Teal-coloured sides, reduced white in front of black vent (that was tinged rust in field) and lack of spotting or other marks within rust sides all pointing to Cinnamon rather than Blue-winged Teal as the non-Shoveler parent.

Joern's drawing below is based on 12 birds from North America and Europe, presumed to have this parentage and confirmed by a photo of a captive bred hybrid Shoveler x Cinnamon Teal from the Natural History Museum at Tring, England. That bird with known parentage matches the wild ones exactly.

Joern tells us that while plumage pattern and coloration was quite constant, iris colour in this cross seemed to vary.  Some of the wild birds had a yellow iris but other had an orange or red iris.  Also the width and length of the white facial crescent showed slight variation.  Several of the birds had a slight dark spotting to the breast.

Blue-winged Teal x Cinnamon Teal

Steve informs us that this hybrid is one of the commoner hybrid ducks in western North America.  I guess that this may have something to do with the facts that (a) the two species are closely related so more likely to produce hybrids and (b) the males are sufficiently distinct that any hybrid male is relatively easy to detect.

The next one was apparently very aggressive, chasing every male Blue-winged Teal that came within 10 feet of it, as you can see in the lower photo.

Another quite typical example here.  The Cinnamon Teal heritage is fairly obvious; Blue-winged Teal given away by the colour in the head and the spots on the sides of the breast.

This tame bird undoubtedly originated in captivity (Blue-winged Teal is a very rare vagrant in the UK and Cinnamon Teal hasn't been accepted as occurring here naturally, though it probably has; both parent species are popular in captivity).  It has been displaying vigourously, sometimes on its own, sometimes with Mallards but most often to a female Mandarin.
