Waxwings in the city

Every year they come to the park to eat the fruit of the Mistletoe, ヤドリギ, the Japanese Waxwing, ヒレンジャク　It looks similar to the Bohemian waxwing, but the yellow tip of the tail is red and so is the vent. There are often a few Bohemians in a flock, but I didn't see any this time.
