Baltimore Orioles are being seen in the metro area. You can bring them in for a close look by offering them grape jelly. It's an early substitute for the fruit they would eat if it was available. We made our jelly feeder in about five minutes. The container once held deli olives. Two holes were drilled to accommodate the perch, an old paint brush. Trying to poke a hole with a knife is likely to shatter the plastic. This impressive feeder is attached to our deck railing with a foot of string. The perch is necessay to help keep the bird from standing in the jelly. The oriole will have no way to clean himself if it becomes a sticky mess.
