While watching and photographing them, I saw an antithesis of bird-life such as I had never imagined. The score of vultures fought and tore and slid about in the black noisome mud exposed by the low tide. Sometimes they were almost back downward--fairly slithering through the muck to seize some shred of fish, hissing venomously; and at last spreading filthy, mud-dripping pinions to flap heavily away a few paces. In disgust at the sight and sound and odor, I started to turn back, when in the air just above the fighting mass, within reach of the flying mud, poised a hummingbird, clean and fresh as a rain-washed blossom. With cap of gold and gorget of copper, this smallest, most ethereal, and daintiest of birds hung balanced just above the most offensive of avian sights. My day threatened to be one of emotion instead of science. Berbice vouchsafed one more surprise, a memory from the past which appeared and vanished in an instant. One of the most delightful of men was taking me out to where the hoatzins lived. We went in his car, which, and I use his own simile, was as truly a relic as anything I have mentioned. I have been in one-horse shays. I have ridden for miles in a Calcutta gharry. I was now in a one-cylinder knockabout which in every way lived up to its name. It was only after a considerable time that I felt assured that the mud-guards and wheels were not on the point of leaving us. When I had also become accustomed to the clatter and bang of loose machinery I was once more able to look around. I had become fairly familiar with the various racial types of Guiana, and with some accuracy I could distinguish the more apparent strains. Halfway through the town we passed three girls, one a coolie, the second dominantly negroid, while the third showed the delicate profile, the subtle color, the unmistakable physiognomy of a Syrian. She might have posed for the finest of the sculptures on a Babylonian wall. I turned in astonishment to my host, who explained that years ago some Syrian peddlers had come this way, remained, prospered, and sent for their wives. Now their children had affiliated with the other varied types--affiliated in language and ideas perhaps, but not, in one case at least, at the expense of purity of facial lineament of race. As I have said, success with the hoatzins came swiftly and completely. We had discovered a few nests with young birds of just the right age and in positions which left nothing to be desired. Yet when a jovial Scotch manager came with news that one of his coolies knew of colonies of hundreds of breeding _anaquas_, we decided to take the whole of the proverbial cake instead of being satisfied with our generous slice. So we made all preparations and left Colony House early one morning.
