Excellent, thanks for sharing!
Hopefully their numbers will spring back and it's not something like pesticides or new predators (humans?) that are hurting them.
I've lived in rural AL in the U.S. for 14 years and saw only a few turkeys and cottontail rabbits for the first 10, have now seen more in the last 2 years of both than I did in the first 10, so they're on the rise.
In that time, however, have seen less quail and heard fewer chuck-wills-widows and whip-poor-wills. Hopefully they'll come back too. It seems that the numbers of all the wildlife, at least around me, fluctuate every few years.
Possibly the rise in red and grey fox sightings account for the fewer numbers of quail and other ground-dwelling birds. Nature has a way of balancing things out as long as man doesn't wreck things too much.
