Good job in protecting the Snowy nest...
I studied the Piping Plover in SOuth Dakota in college....my long time favorite bird. It's happy little voice Peee Leew is etched in my memory.
I did a spring/summer study at Clay COunty park on the Missouri River outside of Vermillion South Dakota (USD). What a great time that was...I'd ride my bike out to the park, make my rounds checking each nest, wading or swimming the channels between sandbars. Watching each nest from a distance with binoculars, observing courting and nesting behavior. The small colony covered about a three square mile area with nests about 1/4 mile apart dotted in this web of large exposed sand bars. The plovers preffered the low wide flat sand bars with a band of marsh grass on the edges. Sand bars with more established vegitation were avoided. I wanted to video a hatching but couldn't get permission to use the video equipment in the wild...By midday I would wander back to the beach areas and my art student buds would be showing up to party...and I would hang out with them the rest of the day, bumming beer and snacks sometimes I planted a cooler of beverages in the woods for later if I drove out...I didn't tell anyone the locations of the nests or my beer cooler... :) Most folks didn't swim the 30 yard wide channel get to network of sands bars. It is a extremely beautiful place. Fine sand, clear water and marsh grasses....tons of birds...
I was this long-haired "bio-major" always at the park.
I counted the eggs in each nest and determined percentaged hatched and natality rates. I did this over the summer and follwed the status of 8 nesting pairs and thier broods. They did quite well a high percentage of young survived. ONe nests was destroyed by human traffic the parents went somewhere else out of my area. Egg shell thickness of hatched chicks were above normal and the average brood size and the eggs themselves were a bit larger than data from other regions that I had. I concluded that the population was healthy and thriving as long as the habitat remained intact and human recreation pressures kept in check during nesting season. Luckily that is early enough that it is a bit cold for many to be roaming around the sand bars late spring. After the young hatch they quickley are up and running and eating. After a few weeks they were difficult to find again. One had to watch an adult carefully and look for the other near open area edges...the chicks hide very well. Once they fledge they seem to leave the area and only occationaly did I see a bird as summer wore on.
The big issue with these birds (plovers) is that the nest being in sand with small pebbles at beach areas are suseptable to ATV and foot traffic. The birds are good at drawing people away from the the nest and preveting it from being discovered by a passer by but can't stop a beach football game or a constant stream of ATVs....
I did that study the spring and early summer of 1984 and the area is listed as a "critical habitat" for the species by USGS in 2002.
When I completed the study I presented the findings that fall during my bio major, "Senior Seminar" class with drawings and slide show. I was laughed at by the Pre-med students when I raised the curtains on the drawing boards exposing my hand drawn maps and birds. (art minor so they were rather good I thought)
The PreMed snobs stopped laughing fast after and all of the popular zoology Profs showed up to see my presentation as they knew I was doing this study and were always asking how it was going. They helped me a lot with equipment and resources and what to observe and how to observe. I took the entire hour and fielded questions (normally two presented, "maybe" one prof would attend.) My seminar was the only one that wasn't a "high school" term paper being read. I got an A and some of my best memories of my college years.
I went on later to be accepted into a progam to study marine biology in "three seas", East Coast, West Coast and Jamacia I was going to focus on coral ecology...unfortunately that was one of those life decisions that a young man allowed himself to be influenced by others and was convinced to not go...I regret that to this day.
and that is something in my life that I need to make right...
