Martin Identification

["kbrandwood" <>]

HI All/Max, another ID point re the Martins which both have white rumps, 
however the rump of the Tree Martin as a soiled look about it where as the 
Fairy is bright white, the Fairy is noticeable smaller when seen in flight or 
perched, I find Martins also have a more gliding flight than Welcome Swallows. 
Time in the field looking at them Max, invaluable.
