Photos of poor quality, but containing 2 WWCR males. Note in particular, dark lores, smaller slimmer bill than typical for RECR, and slightly deeper pinkish red hue. Please also note that in this image, scapulars and coverts of lower individual are obscuring white wing patches. While heavily silhouetted, these features are more visible in 2nd image. In observation of birds, both with large distinct white wing patches visible both perched and in flight as opposed to slight cream edging often seen on coverts of some SY RECRs. When taking off both birds also gave distinct WWCR calls clearly different from RECR flight calls.
