Nestlings continued

Feed me, feed me, feed me!! Non-stop.

I wasn't quick enough. One baby presented rear end to nest opening and let loose a fecal sac which caught in the nest straw. I've seen robins do this, but never before seen a baby sparrow that's house trained. However, if they're tiny this must  mean that the parents keep the nest clean.

Quick enough for this. The parent arrived with food, fed baby and then flew off with fecal sac. Hooray for housekeeping.
