I watched for a long time last night. She left several times and returned with Larvae of some type that are plentiful and easy to catch (according to the website). It should not be too long before she can leave the little one alone for longer and hunt for larger prey that the chick will need. I hope the little one can hang in there for a while and get to that point. The website monitor feels that the other eggs will not hatch, it has been too long. The last thing she needs is more hungry mouths to feed. I still hope and pray for this pair.
