Rufous-naped Wren


I think that when I wrote, “we birded in the garden in the back of the Bougainvillea Hotel,” that you do not have an appropriate vision of how luxuriant it was. In the 30 minutes we had on our first evening between rain showers and an hour on Sunday morning, we saw six bird species—and 16 the next morning. 

One interesting bird was the Rufous-naped Wren. This species often nests near wasps, which provide the nesting birds with protection against predators. Rufous-naped Wrens are found from southern Mexico to northern Costa Rica. Compared with more northern populations, the Costa Rican birds are hardly marked below and have the rufous on their napes extending onto their backs. Their calls also differ. Many ornithologists now consider them to be a separate species, the Rufous-backed Wren. In any event, this bird was common in most of the northwestern Costa Rican locals we visited.
