They all appeared to be females and juveniles, maybe twenty or more. They were also in the cherry and osier, presumably after berries. The target of the orioles in the Trumpet Vine was a little different. They were taking apart the blooms for the sweet parts.
But, more was revealed by the photos. They had a wider diet - ants. Look at the beak of this bird.
Mixed with the fascinating display of Baltimore Oriole behavior was another visitor to the flowers.
On occasion, the Ruby-throated Hummingbirds would land and crawl up onto the flower to reach the nectar. The activity continued for about twenty minutes before the Orioles moved on to new grounds.
I had passed on a trip up to a natural area this morning with the intention to get some chores done. The unintended consequence of staying home outweighed the importance of doing those chores.
