A versatile item 16 birds in all which include 8 cardinals and 8 white birds. Use them on your christmas tree or patio or w ever else. When I plugged them in they light then they don't light then some light but have no fear. These birds are removable and can be placed on top of your already white lights on your tree or pick up a strand at a Home Depot for only a couple of dollars. I'm including the string of lights so you can see how easy it is to put them on and take them off. Who knows they may light up all fine for you. Bird measures 5 inches x 1 1/2 inches. Moving sale item. Packed weight is 2 lbs. Thanks for looking and good luck bidding.
