Twig nest in a goofy location, I'm guessing wrens.
Swallows? Although that doesn't seem like a place where swallows would nest.Not baby's this time, just a nest. If it's the same bird as I seen a couple three weeks ago in the same spot, they are black and dark blue. Really fast darting fliers.
TIA
Hummingbird is even worse! Humbobs!It would take several of those to make a decent appetizer.
Have you found any others?
