There's a beach near our home which is popular with local people. It also has a small lake and some scrub around it. Last year I found a Large-tailed Nightjar using the area as a daytime roost, and this year, I have found that they are nesting there. Even when you know that the bird is there, it is amazingly hard to spot, as their cryptic plumage blends in perfectly with their surroundings.
My first visit was on March 23, when I discovered the male sitting on two eggs. By the end of the month I found parts of an eggshell where the nest had been, and the adult bird was sitting in a different place. I assumed it was sitting on the young, but did not see them.
