Having just purchased the Canon 600 II, I'm learning more about birding. I've always enjoyed it. I've had feeders in my yard for a long time.
I usually stay on my deck about 20-30 feet from three feeders.
My question is: is it okay to seal off the rear facing ports so I get better vantage shots? It sure does make expensive food last a lot longer. But with large black birds eating, are they just intimidating the smaller birds?
I also put up a humming bird feeder and they were there within one day. I haven't covered any of those openings but am considering it.
