It appears that the timing of the four day gap was perfect as there has been very little passerine movement lately. The banding totals for May 10 and 11 were 23 and 26, respectively. Yellow-rumped Warbler has been the most numerous species together with some late Ruby-crowned Kinglets and White-crowned Sparrows and early Orange-crowned Warblers. Northern Waterthrush and Wilson’s Warbler were new species for the spring.
Outside the nets the most notable change has been the appearance of shorebirds. Both Greater and Lesser Yellowlegs are now frequenting the area and small flocks of various species, including Solitary and Pectoral Sandpipers, have been seen flying over the site. A Swamp Sparrow is singing in the marsh and Tree Swallows have found the nest boxes.
