Presence of conspecifics, time of day and age affect willow tit food hoarding

Article Abstract:

The willow tit, 'Parus montanus,' avoids hoarding food in the presence of conspecifics. This is probably caused by willow tits' perception of conspecifics as potential kleptoparasites or pilferers. However, the presence of birds of other species does not affect their hoarding activities. Yearlings also store more food than adults probably because they are more subject to kleptoparasitism by more dominant adults.

Alarm calling by willow tits, Parus montanus, as mate investment

Article Abstract:

A study of the response of captive willow tits, Parus montanus, to a lifelike stuffed sparrowhawk, Accipiter nisus, shows that willow tits primarily give alarm calls to warn a mate. Alarm calls, given more often by adult birds than by juveniles, serve as a form of mate investment, as implied by the frequency of calls given by adult males when they see their mates.

Differences in mate guarding between age classes in the willow tit, Parus montanus

Article Abstract:

A study of the mate guarding patterns in willow tits revealed that adult males spent more time singing and less in mate guarding. However, juvenile males displayed increased levels of mate guarding, thereby suggesting age-related factors and benefits as possible causes of this contradiction in willow tits' behavior patterns.
