Fig. 6. A box plot showing the distribution of flight speeds as they vary with
distance from the nest. In (A) the flights are pooled and divided into bins of
10 cm increments increasingly far from the nest Each box extends between the
lower and upper quartiles of flight speeds, with a line at the median and
whiskers showing the range. Near the nest the median flight speed was low
(14.5 cm s–1, while closer than 10 cm) about a third compared
to speeds far from the nest (43.1 cm s–1 while between 50 and
60 cm). (B) These speeds broken down into vector components parallel and
perpendicular to the axis of the nest. Each measured absolute speed in A is
the square root of the sum of squares of the components in B.
