Birded Harford Glen Sunday AM, April 4. Warblers were of particular note: Yellow-Rumped - at least 20 observed, many more singing. Palm Warbler - 10-12 individuals Northern Waterthrush - 1 singing Pine Warbler - 1 singing Northern Parula - 2 singing *** Canada Warbler - 1 male ID'd at very close range (20'). No Yellowthroats or BG Gnatcatchers, however. Also no Solitary SPs, which is what I went there for to begin with. Brian Monk Bel Air MD 410 836 7033
