It was a busy day at MMLD when a baby cat bird fell from its nest and landed in our parking lot. Fortunately we scooped it right up and put it in a little basket and attached it to a tree all while Momma cat bird was watching and squalking at us. I peaked out back several times to make sure she knew baby was in there a she continued to feed him but never saw her actually go near the basket… she was all around it. Well, thankfully tonight I stopped by and there was Momma perched on the edge of the basket feeding her baby. My heart is so happy! A HUGE thank you to Bonnie Buckley (who just happened to pull up to our drive thru when all of this was happening, she guided us through getting baby to safety). ... See MoreSee Less
