Abstract: | Distance-dependent prey detection was experimentally studied in the red-backed shrike (Lanius collurio L.). Maggots were presented at varying distances and the time a food-deprived bird scanned for prey before attacking it was measured. The probability of detecting a prey decreased with increasing distance. There was a tendency for less precision in the strike with increasing attack distance. There was a greater probability that the birds would detect a prey at a given distance from a high perch than from a low perch. Prey concealment reduced the detection probability. Detection time for a prey increased significantly with increasing predator-prey distance. Several of the findings are consistent with the predictions of an optimal predator search model (Andersson 1981). |
