Poecile palustris / Poecile montana
This is one of the smallest bird coming to our feeder. This is some sort of tit but I can’t tell whether its Willow tit or Marsh tit!
More pictures here.
They both are so similar. Both have a black head and black spot under the beak. Some say the only way to tell is the song or Willow tit has a brighter line on wings. Still can’t tell what’s coming to our feeder whether it’s willow tit or Marsh tit.
