Getting ready before they arrive
The week before April is the time to act. Have feeders cleaned, filled and out by early April — the first Bullock's orioles into Kansas are scouting for reliable food, and a station that's ready early gets added to their route.
Once nesting begins around May, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.
