Song or voice of the European Honey Buzzard

It is usually a silent bird, with a high, drawn-out whistle, clear and slightly melancholy: «flíuu».

The sonogram draws the sound: time runs from left to right, and the higher a trace sits, the higher the note.

Flight of the European Honey Buzzard

It flies with deep, springy wingbeats, and glides with wings arched or flat and the tips drooping. On migration it climbs in circles on thermals and launches from the top, in a straight line, to the next one. When in display it claps its wings above its body in mid-air, in a sort of applause.

  1. It lets itself be carried by the warm air and circles widely, with flat, slightly drooped wings, hardly flapping them.

  2. From on high it glides in a straight line, losing height little by little, until it finds the next thermal. The groups pass one after another.

Identification of the European Honey Buzzard

Habitat and distribution of the European Honey Buzzard

The European Honey Buzzard ranges across all of Europe except northern Scandinavia and Iceland. Also in western Asia. It tends to settle in extensive woods, above all deciduous ones such as beech woods, Pyrenean oak woods or birch woods, with clearings of shrubs and scrub or grassland. It also appears in hilly wooded areas, from sea level up to about 1,700 metres. It is present from April until it leaves in September. Migrants cross the Mediterranean on regular routes.

The European Honey Buzzard usually hides when breeding. It is easier to see on migration when it concentrates at the straits over the Baltic and the Mediterranean, on its way to tropical Africa.

Etymology of the European Honey Buzzard

The scientific name says almost everything: «Pernis» is a Greek word for a bird of prey, and «apivorus» is «bee-eater» in Latin, from «apis», bee, and «vorare», to devour. In Spanish, abejero, the one in charge of the bees, although the ones it really attacks are wasps.

Population of the European Honey Buzzard

In Spain about 1,850 breeding pairs are estimated, and the trend in Europe is stable1. It is included in the List of Wild Species under Special Protection and appears as Near Threatened in the Red Book of the birds of Spain. In Cabañeros we only see it passing through.

Nest of the European Honey Buzzard

It builds its nests of twigs in the foliage of trees, usually in the upper half of the crown. Sometimes they use old crow nests.

Courtship and breeding of the European Honey Buzzard

They lay a clutch of 1 to 3 eggs between May and July–August, months that coincide with the greatest abundance of their prey. In April and early May the first birds arrive from Africa. These are the males, which when the breeding season comes show a solitary and aggressive attitude, nothing like their gregarious character during migration. The courtship phase begins when the females appear. Afterwards, the pair rebuilds the previous season’s nest.

The eggs are white, speckled with brown, reddish or violet spots, and are incubated for about 37 days by both birds, although the female usually spends more time on them. The chicks take about 40 days to fledge fully and get ready to migrate at 70 or 75 days old.

Diet of the European Honey Buzzard

Its diet centres on wasp nests and honeycombs. The shape of its bill, short and thin, lets it extract the pulp of the combs easily. Its toes are protected by hard scales to avoid the stings of these insects. It eats wasp larvae, bees, honey and wax. It also feeds on adult insects, such as spiders and worms, as well as small mammals and reptiles. Sometimes it even eats fruit.

Curious facts about the European Honey Buzzard

The European Honey Buzzard in Cabañeros

In Cabañeros the European Honey Buzzard is present during its migration. It is quite frequent during the pre-nuptial passage, which lasts from early May to the end of the month, and the autumn one, from 15 September to early October. They are gregarious, forming groups of up to 70 birds that pass through without a break.

Where to see the European Honey Buzzard in Cabañeros

They usually take advantage of the updrafts that rise on the slopes of the Cuerda de Miraflores and the Sierra del Chorito to cross the park from north to south.

When
Only on the migration passages: throughout May, heading north, and from 15 September to early October, heading south.
What time
From midday to early afternoon, when thermals are at their best and the groups climb in circles.
Where
On the slopes of the Cuerda de Miraflores and the Sierra del Chorito, where the updrafts form that they use to cross the park.
What to look for
A bird of prey with a small, cuckoo-like head and a long banded tail, climbing in circles with wings flat or slightly drooping; if there is one, there are usually more behind.

How to tell them apart

Sturdier, with a round head that does not stick out, a shorter and less barred tail, and a dark patch at the wrist. It glides with its wings in a shallow V and is usually present all year.
