The Grey Heron (Ardea cinerea) is of the family Ardeidae and is in the genus Ardea.  It is resident in the temperate regions of Eurasia as well as eastern and sub Saharan Africa. The more northern populations are migratory and move south for the winter. Wetlands are its main habitat and commonly occurs along estuaries, streams, rivers and lakes. Aquatic as well as terrestrial creatures are preyed upon. Prey items include amphibians, insects, reptiles, small mammals and birds which are swallowed whole.

This species nests in tall trees in colonies which are known as heronries. Upto five eggs are laid and are incubated for 25 days. Fledging takes place after 60 days.

The Buff-tailed Bumblebee (Bombus terrestris) is of the family Apidae which is in the genus Bombus. This species is commonly found throughout the temperate regions of Europe, The Middle East, northern Africa and has been introduced to other countries including Australia (Tasmania), Japan as well as parts of South America. 

It is not normally seen in Ireland during the colder months of the year. In late autumn the worker bees and the males (drones) die off and the gravid queen hibernates for the winter. In recent times, it has been on the wing all year round mainly at coastal locations where shrubs such as Hebe (Hebe × franciscana), Gorse (Ulex europaeus) and Fuchsia (Fuchsia magellanica) have continued to flower in mild winters.

Aquilegias produce their nectar in spurs which project from the rear of the flower head and are pollinated by long tonged insects, including hawkmoths. Short tonged insects, such as bumblebees, use a method known as nectar robbing and penetrate or cut into the plant's spurs to extract this rich food source. As a results no pollination takes place. In North America aquilegias are also pollinated by hummingbirds.
