With Bonaparte's Gull.
观察细节
*Rare. Seen earlier today by Tim Lenz. Was not seen on my initial pass along the south side of the island. County bird, and nemesis county bird at that. Initially seen from the south side of the island (after portage), feeding in the center of the bay, drifting north. It stayed close to a few Bonaparte's Gulls. It landed once for about 30 seconds on the island and was a distance from me, then took off. About 15-20 minutes later, it returned and rested for longer, with closer views and better photo opportunities. Obvious tern, smaller than nearby Common Terns and Bonaparte's Gulls. Shorter tail, dark gray/blackish wings, black spot behind eye around auricular, interesting incomplete eye ring-type pattern, and brownish present along back, indicating juvenile. Overall darker than Common Terns, very buoyant flight.
