I would like to discuss the event between 00:00:05 (approximately 2012-05-16 13:35:07) and 00:09:25 (approximately 2012-05-16 13:44:27).



I could not see anything on the nest

The grouse are pretty well camouflaged and can be difficult to seperate from the background.
The common windy days blowing the grasses around also make it difficult.
Also, the hen will pull grasses over her to give shade and hide the nest while she is on it.

What you are looking for in this case is when a patch of "grasses" move at once and in a different direction than the breezes are blowing, indicating that the grouse has adjusted herself on the nest. Or if a patch doesn't move at all when all the other grass is moving, you will be able to see feather patterns.This will help you identify parts of the bird that may be showing through the grasses.
The time of day (early afternoon), makes it further difficult because they can go for hours withiut hardly twitching a feather.

Anyways, the parent is On Nest for this entire segment. Parts of the feather pattern are visible for most of the video just below center.

Often times it is impossible to discern exactly what is there until you see the parent leave the nest, usually at first light and again before dark. They are very good at disguising their nest from preditors like the hawks.

Yes, the grouse are really difficult. To add to that, this was the first year of the grouse project and we weren't great at camera position that made it easier to watch the nesting females. She is there but no doubt, it is hard to tell. In some cases, you may not be certain and it is great you asked about it. The North Dakota wind and dense grasses (which are good to protect the female and her eggs from hens) make it tough for us to know what is happening at the nest. Many of the other species are a lot easier to see and videos that happened after 2012 when my team got better at camera placement for watching activities besides identification of predators.
