The two hummingbird babies in our backyard started out fine a few weeks ago.
But as time passed, one baby grew stronger and started taking over the nest leaving the other one with less space and having to hang over the side. The mother appears to be feeding both chicks as we sit and observe from a distance, but the one baby just did not mature at the same rate as its sibling.
After three weeks in the nest, the stronger one fledged and was able to fly away while its weaker sibling has not developed "normally". The mother no longer appears to visit so we will be taking him/her in and hand feeding it.
