To facilitate and promote consistency in data collection and the
interpretation of nest results, MWDI provides forms to establish
project site box profiles and to monitor & analyze results.
Please download Field Inspection and Nest Box Profile forms from the links below. These forms are provided in both Microsoft Excel and PDF formats and are set up to be printed at 11" x
8 1/2" (letter - landscape).
Nest Box Profile Form
TheNest Box Profile Form spreadsheet provide a way to develop a
numbering sequence, by area and by the basic box facts:
Predator guard type and condition
Box placement category
The form also includes many other qualitative items such as
access issues (hip boots, chest wader, boat, ladder
requirements, tide issues - by box as needed, projected repair
scenario, predator issues, distance between boxes and other
things to watch for.
The box placement category "Visibly Isolated" is somewhat
subjective but it does provide an important piece of information
on which nest results often hinge. If a box is visibly isolated,
i.e. well hidden, it may relate to future nest dumping and/or

Nest Inspection Summary Forms
MWDI Field Inspection Forms Excel Worksheet includes an example
with explanatory notes, a blanks sheet showing summary results
desired, and a blank sheet with no summary data sections.

Note: For one-time or final nest inspections, certain
information is not needed. However, information about nest type
(Normal or Dump) and Nest Cover (None, Nest Material, Down) are
very important diagnostics to record as final and chronological
nest progress indicators.
For example, nest abandonment analysis is facilitated if nest
progression is known and the number of eggs left behind or how
they look when destroyed is described. Consider the following
If down is left in a bowl-like shape not covering all eggs (with
duck poop on them), this is very telling! It means the hen
was scared off the nest and never returned.
A normal nest (15 eggs or less) with down covering all eggs,
but abandoned, is an indicator that the hen may have been
killed while away from the nest, as everything left behind
was in good order.
A nest with down and all eggs hatched or with membranes
strongly suggests snake predation, as the hen got to the
incubation stage (e.g.. the down covering) but the snake ate
them all and left.
A dump nest with no egg covering strongly suggests nest strife
as an abandonment reason, especially if several eggs are
cracked and/or yolk is spread around the box.
A nest with 1-3 eggs and no cover strongly suggest a "drop"
nest, one which the hen(s) never intended to incubate but
perhaps wanted to hedge their productivity risk by leaving
an egg or two for another hen to take over.
We are routinely revising these forms to make them more
user-friendly and relevant. Hopefully, this will simplify your
own personalized forms development. If you have suggestions for
improvement or any questions regarding the use of the forms
or how to submit completed forms, please let me know via email: Cliff Brown at
