The
bluethroat is a dimorphic passerine where males have a distinctive throat patch which is displayed to males in a male-male competition and also to females, which are less colourful than males, during courtship display (Peiponen 1960, Andersson & Amundsen 1997).

Bluethroat PIC: EPHRAIM PERFECT AS May turns into June, with the bulk of spring migration over, this can be a period of surprise rarities.
Several bird species such as flamingos, Northern lapwing, European roller,
Bluethroat, White-throated robin, Eurasian hobby and Pacific golden plover can be commonly viewed during this season, which is a rare feat for a desert nation.
Factoids included in this information are, for instance, that the Robin and the Blackcap are among the few birds that sing in winter, or that the
Bluethroat can imitate the sounds of other species and even mimic the sound of reindeer bells.
The
bluethroat, on the other hand, is a winter visitor, and the migratory honey buzzard only passes through.
Juvenile
Bluethroat Wrasse Notolabrus tectricus up to 15 cm long were a common prey, and one other fish taken appeared to be a Crested Weedfish Cristiceps australis, which occurred in the permanent tide pools.
