Colour bands, mate choice and paternity in the bluethroat

Article Abstract:

Any impact of colour bands on paternity in bluethroats, Luscinia s. svecica, appears to be very weak. Research involving paternity analyzes of birds involved in a colour band field experiment found that the previously reported effect of colour bands on males' perceived threat to paternity did not show itself in a difference in actual paternity. There was no significant preference for males with colour bands in either year or in the combined data set.

Coloured leg bands affect male mate-guarding behavior in the bluethroat

Article Abstract:

Blue and orange colored leg bands were attached to bluethroat (Luscinia s. svecica) males to test the assumptions that these males would have a higher pairing success, guard their mates less intensely and display more advertisement behavior than males given non-ornamental color leg bands. The findings reveal that males with ornamental bands invested less in mate guarding and spent more time advertising themselves by singing, performing song flights and encroaching upon neighboring territories. However, no difference was found in terms of pairing success.

Fluctuating asymmetry, mate choice and experimental designs

Article Abstract:

Fluctuating symmetry has been linked to mate selection in evolutionary studies of birds and insects. Experimental design of functional ornamental fluctuating asymmetry tests remains problematic due to quantification problems in various traits. Further studies should be conducted on the psychological mechanisms employed by animals for determining conspecific physical characteristics that would influence mate choice.
