Sex: M, age: 1CY+ (euring: 4). Trapped: May, 2020 in Vysočina Region, Czech Republic.

CZEP20-149

Sex: F, age: 2CY (euring: 5). Trapped: May, 2020 in Vysočina Region, Czech Republic.

This individual looks like a bird in juvenile plumage. But considering the date of capture (begining of May, actually it was at the time Shrikes began to appear that year), bird in juvenile plumage is very unlikely. I am ageing this bird as a second year because of that much retained juvenile contour feathers.
