    For our robin group we think that, a pair of adult robins potentially produce one hundred and ten babies if they survive a ten year life time because two to three nest a year with four to five eggs each. 2.5 nests
                                         x 4.5 eggs
                                        ***************
                                           125
                                         1000
                                        *********
                                         11.25
                                        x10
                                        *********
                                          110
        So potentially they can produce 110 babies in a 10 year life span.
