Journal 3/1 E Borell Ojo Laguna, Chihhua, 963 5000 ft el. Mexico March 19. It is surprising how cold it remains at this date. Again there was ice on the shallow ponds. The thermometer said 26°F at 7 am and only 50° at noon. There is considerable difference in the leaf development of cottonwoods; on some these leaves are ½ to 1 developed, others are still in the catkins stage. The willows show the same difference in development but are less advanced than the cottonwoods. The mesquite & cactaceae are still completely dormant for outward appearance. Made a trip to the nearby ponds and also to the big lake, of the pools near camp saw 10 green-winged teal, 6 Black ducks and 4 blue-wing or cinnamon teal. The latter all ♂, Brewer Sparrows & Wilson Snipe still present in usual numbers Roadrunner observed one at close range; it streaked breast indicates Californicus
