Figure 1. The number of occupied nesting structures in each study area. Northwest Pennsylvania had 180 available structures and southern Ontario had 170. Stempka adds, “Hen houses are a relatively inexpensive, tangible product that wildlife managers can provide to people interested in helping waterfowl. Hen houses may give managers an opportunity to get to know landowners, encourage their interest in waterfowl and perhaps inspire them to enroll in conservation programs.” This summer Stempka monitored about 185 structures in five counties: Butler, Crawford, Erie, Lawrence and Mercer. The location of each nest structure is marked using GPS coordinates and Stempka checks each nest about every 20 days. Once a nest has at least one egg, it is checked every 5 to 7 days until it hatches. He says he’s spent a lot of time and miles behind the wheel. Stempka attempts to capture and leg band all of the hens nesting in hen houses, both mallards and wood ducks. He sneaks up to the nesting structure with a dip net in each hand, then quickly covers both ends of the structure and, if all works, traps the exiting hen in a net. In cases where the hen has been quick to exit and jumped the net, a remote trigger and two pieces of wire fencing that drop to cover the cylinder ends trapping her inside have been substituted. Each captured hen is fitted with a standard leg band, which will help identify her if she returns to a hen house next year. Then, to reduce nest abandonment, her head is tucked under her wing and she is rocked back and forth until she relaxes before being placed back into the hen house. Stempka can estimate the hatch date for a nest by candling the eggs. He holds a cardboard toilet paper tube up to his eye and places an egg across the other end, then looks toward the sun to examine the silhouette of the chick inside. Based on the size and shape of the embryo, he can pre- Hatched or predated? These mallard eggs have hatched successfully as evident by the intact leathery shell membranes and the round shell caps. mallard eggs 10 GAME NEWS
