dict a hatch date and, because all the eggs will hatch at the same time, he has a good idea of when to come back and check on the ducklings. Stempka also notes the number of eggs that are present, hatched and infertile, and whether a nest has been predated, abandoned or successful to determine the production of each structure. When a mallard nest is due to hatch, Stempka returns to web tag the ducklings. If they haven’t hatched, he checks their progress by candling the eggs and holding them up to his ear to listen for pipping. He also examines the eggs for starring, a small crack where the duckling is just starting to pip through the shell with its egg tooth. If many of the eggs already have small holes where the hatchlings are pipping through, the ducklings can be web tagged while they are still in the egg. A little duckling’s feet happen to be right about where its beak is when it is still packaged in the egg. Stempka just widens the hole enough to gain hold of the duckling’s foot, pull it out of the shell, clip a small metal ID tag on the webbing and tuck the foot back into the shell. If the ducklings have already hatched and are still present when Stempka arrives, he places them all into a small bucket, web tags them on his tailgate, places them back in the nest and covers them with nesting material so they’ll sit tight until the hen returns. Sometimes those web-tagged hatchlings end up being captured and leg banded as juveniles later in the summer at duck banding stations. Stempka also measures habitat variables OCTOBER 2008 Figures 2 and 3. Nest success rates of wood ducks and mallards in each study area. When compared to other research that estimates ground nesting success in the Great Lakes region to be a mere 18 percent, the benefit of hen houses is evident. to help determine what might influence the likelihood of a hen using a hen house. He records information about food abundance, surrounding nesting habitat and land use. He is also documenting characteristics of the wetlands; how much open water there is, how deep the water is, how long the water is there, what type of vegetation there is and what kind of invertebrates are present. He also notes how high above the water a hen house is as well as its distance from other hen houses, the shore and vegetation. The day I spent with Stempka and Jacobs we visited hen houses in the Conneaut Lake area — the largest wetland system in the Common11
