I was surprised to see several pine warblers in Cass county this weekend (April 16). I saw one of them before I saw my first yellow-rumped warbler for the year (April 17). On the evening of April 15th I also heard a northern saw-whet owl calling along with several Wilson's snipe winnowing.
Common loons were calling late into the night. Spring has definitely sprung in northern Minnesota. Deanne Endrizzi vacation home in Longville, MN Burnsville, MN
