EMPEROR DRAGONFLY (Anax imperator) pair mating, Castro Verde, Portugal

Click here for detailed species information
The Emperor Dragonfly (Anax imperator) or Blue Emperor Dragonfly is of the family Aeshnidae which is in the genus Anax. This large and powerful species is a voracious predator of other flying insects. Prey items including medium sized dragonflies, damselflies, butterflies and other flying invertebrates are captured on the wing but it tends to avoid predating bees, wasps and hard shelled flying insects such as beetles. Probably as a result of climate change, in the last 20 years or so it has greatly expanded its range north ward. Now relatively common throughout the Western Palearctic, excluding Iceland and the vast majority of Scandinavia. In the Eastern Atlantic it occurs on all the Macaronesian Islands.

 The Melodious Warbler
(Hippolais polyglotta) is of the warbler family Acrocephalidae which is in the genus Hippolais. It is a common breeding summer resident in southwest Europe and northwest Africa. In Mid September, it migrates south to spend the winter in sub-Saharan Africa. In Ireland it's a rare but annual over shooting spring and autumn migrant to south coast headlands where it needs to be separated with care from the very similar Icterine Warbler (Hippolais icterina) which has noticeably longer primary projections being equal in length to the tertials. Melodious Warbler primary projections are half the length of its tertials.

The Sardinian Warbler (Sylvia melanocephala) is a small mainly insectivorous warbler of the family Sylviidae which is in the genus Sylvia. It is commonly encountered in southern and eastern Europe as well as in countries bordering the Mediterranean Basin. It is also resident on the Canary Islands. Some authorities recognise up to five subspecies. The female, typical of most sylvia warblers, has drabber plumage, it is grey headed with brownish upper parts and the under parts are washed buff. This species normally occurs in shrubby type habitat as well as in parks and gardens.

Up to five subspecies are generally recognised:
  • Sylvia melanocephala melanocephala - Iberia across the northern Mediterranean to western Turkey. Extends into the Maghreb from Iberia, and into Libya from Italy via Sicily. Migrates to the Sahel and oases in the Sahara in winter.
  • Sylvia melanocephala leucogastra  - Canary Islands, resident, probably some vagrancy between eastern islands and Maghreb.
  • Sylvia melanocephala momus - Near East. Resident, some local movements. 
  • Sylvia melanocephala norissae - Fayyum Warbler - probably only a local morph of momus  - Nile Delta region. Extinct since around 1940.
  • Sylvia melanocephala valverdei - Morocco south to the Tropic of Cancer, inland to the edge of the Sahara. Resident, but some seasonal movements.
