I’ve used a repeating sparrow trap since August of 2015. Results so far are 51 HOSP and 25 starlings trapped. Am thinking about getting an S&S controller trap to really ramp up the # of birds caught. Also caught a mouse or two in the repeating trap believe it or not! Funniest thing i’ve seen are hawks landing on the trap with birds in it and trying to take the whole trap away. Thankfully the trap weighs too much!
