As I left the river, I heard the whistle of the beautiful "toledo," so called because its note resembles these syllables, clearly and slowly whistled, with the emphasis on the last two. Following the sound, it led me to a deep, thickly-timbered gully, at the bottom of which was the bed of a brook, consisting now only of detached pools, over one of which, on the limb of a tree, sat a large dark-coloured hawk, with white-banded tail, watching for fresh-water and land crabs, on which it feeds. I had a long chase after the toledo. As soon as I got within sight of it, sometimes before, it would dart away through the brushwood, generally across the brook, and in a few minutes I would hear its deep-toned whistle again as if in mockery of my pursuit. I had to climb and reclimb the steep banks of the gully: but at last, creeping cautiously, and just getting my head above the bank, I got a shot. There were two of them sitting close together. I brought both down, and they proved to be in fine plumage. The toledo (Chirosciphia lineata) is about the size of a linnet, of a general velvety black colour. The crown of the head is covered with a flat scarlet crest, and the back with what looks like a shawl of sky-blue. From the tail spring two long ribbon-like feathers. Its curious note is often heard on the savannahs, in the thick timber that skirts the small brooks; but it is not often seen, as it is a shy bird and frequents the deepest shades. There were several of the yellow-breasted trogon (T. melanocephalus) sitting amongst the branches, and now and then darting off after insects. This species often breaks into the nest of the termites, and feeds on the soft-bodied workers. Another trogon about here, with red breast (T. elegans), has a peculiarly harsh, croaking voice, very different from the other species, and more resembling the cry of a mot-mot. As I rode back over the savannahs to Juigalpa, the nearly vertical rays of the sun were reflected from the dry, hot, sandy soil. Not a sound was now heard from the numerous birds. The shrill cicada still piped its never-ending treble. No wind was stirring, and the air over the parched soil quivered with heat.
