| 520 | a The importance of male presence on their territories for maintaining paternity in their mates' offspring was investigated in the Yellowhammer. Males were experimentally detained for one hour before and during their mate's fertile period. When males were detained, their territories received an increased number of intrusions and intruding males. Also the duration of intrusions increased compared with when they were present on their territories. No difference was found in intrusion patterns between the prefertile and the fertile period. No intrusions were observed during the post-fertile period. The rate of intrusion was not related to number of neighbouring males although young males suffered from a higher intrusion rate when the number of young neighbouring males increased. Old males with much yellow were subject to more intrusions than other males, predominantly by other older males, indicating a cost of wearing colourful plumage. In spite of the low intensity, or absence, of mate guarding found in a previous study of the Yellowhammer, results indicate that male presence on their territories may reduce the potential for extra-pair fertilizations. | |
