Christman, Dr. 1965 2 Agelaius tricolor 3 mi. E., 50' elev. Oct. 2 Washoe Ranch (Lattice Club), 10 mi. S. Marysville, Yuba Co., Cal. These birds were almost entirely males. Also, males were perched on the cattails in the colony area proper in a fairly dense pattern, in places where many of the leaves were tenuous. No special pasturing was observed. Of the males perched on cattails and the ever present coming and going of males is an indication of breeding then nesting colonies should be expected in the denser growths of Typha from the channel between ponds 2 & 3 down to the axles at #1. We tried to shoot a sample of the birds flying back & forth. At #2 we shot 2 ♂ and 4 more ♂ near the house. The pastures of #5 was flooded, with many Brewer Blackbirds. Also, upon leaving at 4 p.m. we saw many tricolors in a pasture 1 mi. E. of ranch head- quarters. It is believed that the tricolors were flying between the well permanent pastures (dairy type) to the colony - a distance of 1 ½ miles. In the early a.m. & after dark in p.m. tricolors roasted in the strings of cattail near the house where Redwings are normally found. They are not prevalent here during the day- only Redwings. I brought back & am freezing 6 ♂ tricolors. 30 June '61 Exact locality: Marysville Quad., 15' R 4 E; T 13 N section 4 (N ½)
