We weren't sure why, but the yellow-headed blackbirds would let us get much closer during the blue hour when they were among the shrubs, than when they were out in full sun among the cattails. After so many visits to their habitat, I enjoyed seeing them in the low light amidst the greenery.
Your cluster is wonderful. Maybe they feel more invisible in the low light, though someone should talk to them about those wonderful, but very visible yellow heads. Beautiful pages!
