  • Confusion Species

    Attached is a link to some photos i took at Titchwell on Saturday. I believe one to be a Marsh Tit and the other to be Willow Warbler. I've had a couple people agree but it would be good for some thoughts from the real experts here.

    Before giving an opinion, what was your reasoning on the i.d. of Willow Wabler and Marsh Tit?

      Primary projection looks good for willow warbler and the farily bold white lines in the wings of the tit points towards Marsh. Seems to be alot less white in the wings of the willow tit, if any.

        I'll buy that, also orangey legs and a strong, bright face pattern.

        It's actually the other way round. Willow Tit often have bold pale margins to the secondaries, whereas Marsh often have a fairly plain wing. But it's not a wholly reliable feature, and in this case is probably just down to the angle, with light bouncing off the edges of the feathers.

        If you look at the base of the upper mandible, there is a small, but clear, white spot. That tells you it's a Marsh. The cheek also seems to be Marshy (but the photo's a bit bright). And if you look at the underside of the tail the outer feather is shorter than the rest, but the next one in is the same length as the others. In Willow, on the closed tail you can see a stepped pattern of several incresingly longer feathers on the underside. On Marsh there's just one step on each side - the outer feather is short, the rest are the same length.

          Thank you for your very detailed response Mafting. That white spot tip will be very handy in the future.

          I will print your reply for future reference.

          Thanks again,
