C. rufinucha & zonotus 6 2 mi. N Tierra Blanca May 21 to that where I found the pair of rufinucha but found no evidence of other wrns. It must be rare in this area but as yet I can see no reason for its being any less common than 1/2 mi. SSW Boca del Rio, except for fact that vegetation is a bit less dense & more open (even in the thickets). Suitable thickets & small trees & shrubs are not common in this region.
