I should just give up with IDing leasts vs pecs in photos. 

Here's a tip: look at the length of the tertials and primaries. In Leasts, the colorful tertials extend all the way to the end of the tail, while on Pectoral the tertials are shorter and the dark primaries are the ones which extend to the end of the tail.

Structural differences are very important, but since you're on the west coast and don't see them a lot it can be tricky

I would say that the tertials are nearly as long as the primaries, as the primaries often don't reach the tail tip in Least. While Pectoral's wing tips also do not reach the tail tip, as Benjamin noted, Pectoral tertials end well before the primaries do, leaving many more primary tips exposed. Also note the more-extensive streaking below on Pec as well as the different color and extent of the pale fringing on wing coverts (not the scapulars, which are not wing feathers).

Well, I did wonder what 'Least' you were comparing it to, since there weren't any other birds in the photo.  :classic_biggrin:
