Wood Ducks at Lynden III

April 3, 2015

This post is the third in a series by Junior Grounds Manager Weston Wagner tracking the behavior of wood ducks at Lynden. Read part one here and part two here.

April 3, 2015 – I noticed two pairs of wood ducks occupying their usual spot on the lake this morning. I have yet to capture a picture of them as they are very wary of human activity. It is possible and likely that these two pairs are the same wood ducks I have been seeing over the past couple weeks. It’s hard to tell but it is also possible that these wood ducks are the same wood ducks that have successfully nested in the boxes here at Lynden in previous years. I have yet to see a wood duck in a location other than the South East corner of the lake where two nest boxes are positioned. If these wood ducks do decide to use these boxes as nesting sites, it will be soon. My guess is they will start using the boxes, especially the ones over the water, next week, if they haven’t already. I won’t check the boxes until late next week to prevent disturbing any nesting activity. Once a nest is established, the hen will lay one egg per day until her clutch is complete. On average, the size of a clutch is usually between 10 and 14 eggs. Once the hen lays all of her eggs, she will begin the incubation process.

Bufflehead duck

Unlike the wood ducks, the lone male bufflehead duck I observed this morning was oblivious to my presence. Buffleheads are a diving duck that feed underwater by catching aquatic invertebrates. One thing they do have in common with wood ducks is that they are cavity nesters. This leaves the possibility that buffleheads are checking out the nest boxes as potential nesting sites as well.
