The two birds cited above furnish the only records which I have been 

 able to find of the taking of this species in Costa Rica. It has been taken 

 in Panama. It would seem that it is a rare straggler along the Caribbean 

 lowlands, at least during the autumn. I did not see the bird again in that 

 region, although I always watched for it.
