If you look closely ....

you'll see a tiny beak in this hummingbird's nest.  She has been returning to feed them every 15 minutes or so.  I struggled to get a decent shot since the nest is so tiny and unfortunately too far away.  A photographer friend of my sister's may be stopping by later, and I'll be curious to see how she fares with this subject.  I realize that since it's the only time I've found a hummer nest on my own, I should be happy just to observe it.
