You know if they would gather the eggs at the very beginning and incubate them, the birds would renest or attempt to. Which is obvious with the number of listed pairs of oystercatchers and number of nest.
This is not exact science, or even close, I am not a bio tech, just a medic, but I have slept in a holiday express before. Let's play devils advocate for a while and try to help these birds out. The Piping Ploves made 14 nest and lay 4 eggs per nest. That is 56 eggs. Incubate those eggs then re release them at fledge time, holy cow would you be adding a ton more plovers to the mix than the 5 we fledged this year. Even if only half of the gathered hatched or a quarter you would leaps above letting them do it on their own.
Now the oyster catchers...38 nest, how many eggs per nest? 1-4 with 3 the average. 38 nest and 3 eggs per nest 114 eggs, another holy cow! We only fledged 9. Think what could be done to increase them if we would incubate the eggs. Even if we only took half the eggs. Oh my goodness.
I have no idea on the terns or skimmers, they do not give us data on them. Also this would work on turtles also, no nest lost to predation or storms.....wow!!
These are not new concepts, they are practiced in other areas run by the NPS. So IMO, not all is being done that could be done, what is being done is what easy for the park . service, throw up signs, trap other animals and let nature take its course. Not helping them to prosper and survive.
Again my two cents, which does not amount to even that really.
