syrup at times of the year when natural nectar sources are not enough for the hive's needs. There are various styles. Division board feeders have a shape similar to that of the frame, and hang inside the hive body in the same manner as a frame. Entrance feeders are wedged into the hive entrance on the bottom board with an inverted container of feed. Hive-top feeders have the same footprint as the hive body and are placed on top of the hive, but underneath the telescoping cover. Other hive-top feeders consist of an inverted container with small holes in the lid, which are placed either directly on top of the frames, or on top of the hole in the inner cover. When harvesting honey or maintaining the supers, an "escape board" or (British) "clearing board" is placed between the brood boxes and the supers to get most of the bees out of the supers. The escape board lets bees exit the supers into other areas of the hive, but makes it difficult for the bees to re-enter the supers. There are many different designs. Patents USPatent|9300—L.L.
