After one day on a recent visit to Costa Rica, my impression was: Where are all the birds?
My friend Mike has seen 798 species of birds in that Central American country. He's been working on that list for years. It seemed to me even more difficult than I had imagined.
Birds there were, certainly. Many hummingbirds, dozens of a species known as green violet-ears. (Curiously, the first time I saw that species was in La Crosse, Wis.) Other species, however, were present in two or threes. My expectations leaned toward at least double figures.
We were spending our first three days at a lodge about 6,500 feet up in the central part of the country. That evening, a large group of bird tourists filled the dining room. It was easy to pick out the guide: He was less than half the age of everyone else.
I intercepted him at the dessert table. (Yes, an entire table covered with dessert; we ate well throughout the week.) I explained my puzzlement.
"Costa Rica has bird intensity," he said, "but not bird density."
There are many species to be seen there — hundreds and hundreds — but generally speaking, not large numbers of any individual.
Costa Rica has a diverse species list because it has diverse habitats. The country runs from sea level to 12,000-foot mountains. Habitat changes with elevation. You don't have to travel far or hike high to find change.
