Something big has nested in our eucalyptus tree. Not sure what type of bird it is. Jack had found a dead mouse in the yard a week ago, and about a month ago Sadie "caught" half a squirrel. Yesterday some creature was squawking up in the tree, which made us notice the nest. I tried to get a look at one of the birds after Megan went down last night, and it may be an owl, because it went off to hunt at sundown. We'll try to take some pictures and figure out what is up there.
