Posting this for Heath Yakstis (hope the spelling is correct).
I ran into Heath at TGP this morning and he mentioned seeing a Black-Throated Blue at Carondolet Park earlier this morning. He saw it around Grand Dr, near a large picnic pavilion and stone building. But the birds are moving around a lot, so it may not be easy to re-find. He said there were a lot of birds in the park.
