Possibly the ability to emit sound that will bounce back to them, similar to that if bats, and allow them to locate prey.
<h2>Mark and recapture method</h2>
Explanation:
Mark and recapture is a technique to measure the size of a population before fishing and hunting season;commonly used by fish and wildlife managers
- It involves the marking of number of individuals in a natural population,returning them to that population followed by recapturing some of those as a basis for estimating the size of the population at the time of marking and release
- Population size can be estimated as(N)=M*T/R
here,M=initially marked;T=total in sample second;R=marked recaptures
There are certain assumptions to this method
- Population is assumed to be closed which means no new individuals were born or immigrated into the population and none died or emigrated from the population
- The chance for each individual in the population to be caught are equal and constant for both the initial marking period and the recapture period
- One of the assumption of this method is that sufficient time must be given between the initial marking period and recapture period for all marked individuals but time period should not be very long
- Animals do not lose their mark
The tags in the given question were estimated a year there is a chance that old marked tags population might have died or emigrated(the longer the time interval the greater the chance) and hence it becomes an "open" population which violates the first law
If proportion of population changes then marked recapture method formula won't turn out be applicable
