We may have a problem!

After being sick and in bed for days, I finally persuaded my husband and kids to go with me to check on the birds that we have invested so much time and love in for the past months! When we arrived, there was only one bird, male in appearance, perched on the starburst. One of our nestlings had fallen out of the nest and didn't make it. Opening the pod, we were very surprised to see conditions much different than previous checks. The pod was FILTHY!!! The mother has not cleaned it out lately and there were 2 dead dragonflies inside. This worried us for quite a few reasons!
1. The mother usually cleans out all th poop and keeps a tidy nest.
2. Only 1 martin flew overhead for a short amount of time.

Now, the babies did not appear hungry, but they were very scared as you can imagine. We put more nesting material in and I am researching what to do! I do not want to assume they are abandoned because someone (maybe the male) has been bringing bugs into the pod, but at the age of our nestlings, I am not sure they are ready to eat full bugs quite yet. I plan on calling wild birds first hing in the morning, but if you have nay advice or ideas, please post so that we can work together to take care of these little ones we have helped to raise! Stayed tuned for more info soon!
