There's always more to learn! This is the first I've heard of Berwick's Wren, and it's a surprise that they are here. It's time to clean out the nesting boxes used mostly by tree swallows. The cattle knocked one off an electricity post. The box was six feet above the ground so the culprit must have butted it down. The others boxes cleaned so far also had nests except one. That one was packed full of small sticks. There was one like that last year also. Curious about this phenomena I skipped Funk and Wagnalls and went directly to Google. This is what I learned.
" If you have sticks sticking out the entrance hole then it means you have a Bewick's Wren nesting nearby. Male Bewick's Wrens will locate possible nesting sites and will show each of them to his potential mates, but it is the female that will choose which of the sites to use for nesting. The male will then fill most of the other nesting sites with sticks to make them unusable by other birds." Google
So, I learned the why of sticks filling a box and they were very packed full and tight. In addition I learned of Berwick's Wrens and that they are present. Who knew? not I.

The Bewick's wren is a wren native to North America. It is the only species placed in the genus Thryomanes. At about 14 cm long, it is grey-brown above, white below, with a long white eyebrow. While similar in appearance to the Carolina wren, it has a long tail that is tipped in white. Wikipedia
