PRIMARY PROJECTION:

This bird shows relatively short projection. Reed warbler PP is 15-19mm

This bird showed exceptionally long projection from Tertial tip. Leg colour quite bright pinkish/yellow in bright sunshine light looking ideal for Marsh Warbler. Ideal PP range 17-22mm

Closed wing view the notch on 2nd primary falls almost level with secondaries. Primary projection is medium length here.
Standard looking PP for Reed Warbler showing medium length.

Adult Reed Warblre showing extensive wear on tail, primaries and tertials
