Owl homes and praying mantis egg casings

A few days ago I went to the Burke Estate with my friend Cecilia and we were looking for praying mantis egg casings and places that owls might live. When we got to the Burke Estate, there were tons of holes in trees for owls to live in. When we got to an area with lots of bushes where we thought we might find a praying mantis egg casing, I started to walk into the bushes and I found four praying mantis egg casings. We brought them home with us by cutting the stick that they were on. When we got home we tied them on bushes so that we can watch them hatch in the spring.
