Shima - Enaga is one of my favorite birds on our planet, and they are a sweetheart looking “Bonnie of a Bird,” and they have a uniquely all-white face and is a sub-species of the long-tailed bushtit. The Shima - Enaga occur mostly in Hokkaido, Japan. But they inhabit the entire Paleatrictic realm. The long-tailed tit is sometimes referred to as the silver-throated tit or silver-throated dasher. The long-tailed tit was first classified as a tit of the Parus group. The Parus has been split from the Aegithalidae and becoming a distinct family containing three sub-group families.
Aegithalos (long-tailed tits) are five species birds with a tail.
Psaltriparus (North America Buishtit), monotypic.
Psaltriparus (pygmy bushtit), monotypic.
The long-tailed tit is insectivorous throughout the year. The Shima Enaga eat predominantly arthropods and prefer the eggs and astronomical huge moths and butterflies, and sometimes they eat vegetable matter.  Outside of the breeding season, they live in flocks from about July to February of half a dozen to two dozen composed of the family (parents and offspring) from the previous breeding season, together with extra adults that help raise the brood. The reason for the flocking behavior is believed due to winter roosting as they are susceptible to cold, and they huddle for warmth on cold nights. When the breeding season begins, the flock brakes up, and the birds attempt to breed monogamous pairs. Females tend to wander into neighboring territories, while males remain within their winter territories.
I photographed these Shima Enaga while leading my annual birding and landscape photography tour Hokkaido 2020. The Nikon D850 was my choice of Camera. My choice of lens was an 800mm f5.6. My camera settings were f/8 1/2000s ISO4000. I would have liked to use a lower iso and a higher f stop, but the lighting conditions were not in our favor, I am looking forward to photographing these beautiful birds next February on my annual Hokkaido winter wonderland wildlife expedition including, Mt. Fuji, Snow Monkey, The Steller's Sea Eagles, other raptors and the Red-Crowned cranes, plus a wide variety of other wildlife, and landscapes.   Namaste, Blain in Japan
