Our thrushes look rather plain compared to your beauties. With those colours they must be hard to spot - especially in autumn.
Have no idea what the Good Lord had in mind when he made males brighter and prettier than females ! Should be the opposite !
Hi Mart, the males are brighter to attract females and most females are browns to hide when on the nest etc. No good shining like a beacon attracting predators. Female kingfishers are one of two birds that have the brighter colors.
