Stalking the Wild Kinglet

[Six grams of bird (half the weight of a Yellow-rumped Warbler): Golden-crowned Kinglet, Stone Harbor, NJ today, with "prey." Click to enlarge.]

These fine-billed birds feed on the tiniest of insects, whether miniscule flies drawn to the "magic" Siberian Elms in Cape May  Point, or equally small insects in the grass next to Stone Harbor Bird Sanctuary, where this kinglet charged me. Or, even better, simply ignored me lying prone in the grass watching its foraging progress.
