Bird-census should never disturb the birds or threaten nests. So I join the opinion of the reaction about the "rope-method". It could be used but only with lots of people and a very slow tempo. But just walking with a "row" of people through a field is as usefull for a census.

A more save method is counting cock-quail that react to a tape of a calling male. It is a simple method and the risk for significant disturbance is minimal. it gives a reasonable result for numbers of cock-quail. For a idea about the sex-ratio you could observe or capture quail in a few tes-areas where the call-respons is different. Some minor statistic will thenm give you an idea about quail numbers. By using the same methods every year (or at least so peridocal that the birds don't get accustumed to the method. preferably no more than once a year better once in two years) you can follow and quntify the population-development without knowing exact numbers of birds (but reasonable estimates, there is literature about the subject). Perhaps it looks a bit "magical" but I guarantee you that you don't have to be a scholar to be able to do these kind of things and it is very satisfying to monitor a species in this way.

Good luck
