Merlin in for a Belly-ache + Sunday, Sunday

[Michael O'Brien caught this Merlin with an impending case of vomiting - which is what famously  happens to birds that try to consume a Monarch butterfly. Only their first time, because they generally never try another one. Click to enlarge.]
A cold front is supposed to pass today, setting up winds going from northwest to northeast overnight. Sunday should be good, and the east component (and cloud cover) could make it a day for Peregrines from the hawk watch, though we are still pre-peregrine-peak-time.
