DeBenedicti's 1964 3 March Playas, Guayas Prov., Ecuador song was a "p'it p'it pre-ee-een pre-ee-een pre-ee-een" which is what the Coril trices do. Seen at all stops, commonest at the two coastal localities. (4) Groove-billed Ani - very common, in small groups at all stops and all along the highway. I did play with half spread, drooped wings & spread tail seen frequently. Sounded weird. (5) Black-culture - white patches in the wing very conspicuous. Only on court in #s. (6) Turkey Vultures - not common as the above and more evenly distributed. (7) Tropical Kingbird - saw only this species for sure, well, at all 4 places, not very common, but easy to find. Grey breast and dark tail. Calls very high pitched. (8) Melodious Blackbird - everywhere and common. short bill, dark eye, purple fringe. They call from a tree a cow-bird like see me see and give a bunting like song that constantly confused me when they flushed; perch in trees, feed on ground. Seen only at the two coastal places, but along the high way everywhere. May be confusing a cowbird with this as well. (9) Morning Dove - at the second coastal stop. 15-20 seen. (10) Yellow Grosbeak - a pair at the last stop on the highway only.
