When can you put out your hummingbird feeder in Connecticut?

In Connecticut, you can typically put out your hummingbird feeder in mid to late April, as this is when ruby-throated hummingbirds begin to return from their winter migration. It's important to have the feeder ready by this time to attract the birds as they arrive. Make sure to keep the feeder clean and filled with a sugar-water solution (1 part sugar to 4 parts water) and remove it in late fall when the birds migrate south.
