    Appendix. Vectors of individual European robins under the various test conditions

    In Tables A1,A2,A3, n is the number of evaluable recordings and αb and rb are the direction and length of the mean vector, respectively. The summary line gives, under αb, the grand mean vector and, under rb, the median vector length of the respective test condition. In the few cases where a bird produced only one recording, the vector length 1.00 is given in parentheses and is not considered for the median. Significance levels compared with control: *P<0.05; **P<0.01; ***P<0.001; NS, not significant (P>0.05).
