Couple of sightings today:

Not sure, need help from my ornithologist friends on this one. Showed up in my back yard. I think it's a pine warbler, but not sure:

And found this alongside Minnow Pond. I'd like to think it's wild plum, but again, need help from my botonist friends because I'm not sure:

Thanks!

Looks like a Ruby-crowned Kinglet.

Looks like a Ruby-crowned Kinglet.

Yup. Juneberry is my guess on the flowers, but I'm not sure. Plum also can be white with a touch of pink.

Definitely not Juneberry. Much larger blossoms. Kinglet it could be.

[Steve Foss]

Definitely not Juneberry. Much larger blossoms.

Couldn't tell the scale from the photo. I'd go with plum, then. In either case, gooooood eatin, short timer!

Well I'm no botanist but my taste buds are top notch. I ate a ton of wild plums from this tree last summer. These blossoms don't look very similar to your blossoms. These have no pink in them, they are all white. Your buds have a star shape feature that these don't have. Also I can't tell how large your buds are but these are a little larger than a pencil eraser. Could it be these are both plums just different species? Most of the blossoms on this tree are on their way out. Could it be that they started out looking like yours and ended up looking like this? Not a very good picture, it is cloudy here in the cities today.

I'm listening! Any other ideas?
