Aww, your birds are lovely Patty and Kate. I must get my tripod set up next to my desk again. I pretty much have the same birds as Patty, but I let the blue jays have their share and still get lots of other birds at different times. I had a family of cardinals this morning, mama, papa and two babies. The bullies at my feeder, are, surprisingly the fat, dumb mourning doves.
I solved the squirrel problem with a net under the feeder. The birds drop a lot of seed, and what the net catches, the squirrels eat. It's worked out well, and the squirrels rarely even try to get at the feeder any more. I want to keep feeding the squirrels because it helps to keep them from raiding my mango tree, where they drop a beautiful ripe fruit on the ground and eat about a teaspoon out of each one then leave them to rot.
