According to eBird, this is not the correct protocol for the use of 0.
0 is supposedly only used to indicate an abandoned or destroyed nest.
Good birding,

I love watching them.

>> Actually there is a way to note the lack of a species in eBird. You can create a list for a particular time & place (like a normal ebird list) and put in the species you observe (if any) and also put in a count of zero for Common Nighthawk. Then in the comments you can put in a statement like you had below. For an example checklist like this see https://ebird.org/view/checklist/S56322729 . Multiple lists like this over the normal time period (days or weeks) that you normally observe the nighthawks would more completely document the lack of nighthawks.
