The bird house was store bought (Walmart). It's the smallest kind (and only kind in store) I could find in Walmart, around June 2019.
I placed bird food in it. Hung around it. There was a mini bird that went in to eat it. I've seen sparrows snooping around inside as well. The squirrels were crazy about the food that I hung outside. It would appear that the squirrel could reach the hanging food. I thought about changing the pole from wood to PVC pipe.
That was when I was about to give up, because there was no nesting. I thought no birds that small would come through to nest in this neighborhood.
Boy was I wrong as I was surprised by this Morning's recordings. The recordings for this camera used to be scarce. But now...wow! I just need to identify this mini bird, same bird I saw the first time.
I shall keep a video journal of it and add them to my Youtube Playlist: Bird House:
My research tells me that these are House Wren.
