During , volunteers re-visited the tetrads covered in the study and recorded the number of Tawny Owls heard. The aim was to replicate the previous survey to allow direct comparisons and to reveal the level of population change over the intervening period.

A study of Tawny Owl calling behaviour was carried out alongside the survey, examining how calling behaviour changed with time of day, month and local weather conditions. BTO collects information on Tawny Owl breeding attempts from roughly nest sites each year through the BTO Nest Record Scheme , with 1, or so chicks and to adults ringed annually, the latter providing key information on survival rates and how these change over time. Methods for monitoring Tawny Owls are being developed by BTO, with a view to delivering a framework for core monitoring of this species across Britain.

By working with local groups and individuals it should then be possible to increase the amount of information being collected and to plug the gaps in our knowledge that need to be filled. This cutting plan, is for an open-fronted design that has been shown to be successful by BTO nest recorders working on the species. Tawny Owl Strix aluco Breeds in broad-leaved and deciduous woodland. Amber-listed Bird of Conservation Concern.

Introduction Calls and identification Ecology and conservation Knowledge gaps and our work Useful resources. Introduction The Tawny Owl is a species that favours woodland habitats, but it may also breed in larger rural and suburban gardens.

Listen to a male Tawny Owl call. Listen to a female contact call. Listen to a male and female duet. Ecology and conservation Ecology Although primarily an owl of broad-leaved and mixed woodland, the Tawny Owl may also occupy conifer plantations, large urban parks and even suburban gardens. Knowledge gaps and our work Knowledge gaps Despite the familiarity of this species, there are important gaps in our understanding, most notably around what is happening to Tawny Owl populations and the reasons behind these changes.

When he cycles past at dusk, his neighbours are switching on their lights. The curtains are open, and the folks inside are watching the news or having dinner. As he cycles on between the sports fields, he hears other Tawny Owls in the wooded North Sea dunes beyond. Arnoud finds a suitable spot and leaves his gear recording all night.

CD is a male hooting close to the microphones at in the morning. Compound hooting of a male. Familiar as these sounds seem to us, we can hardly begin to appreciate what Tawny Owls hear in them. In a few seconds they can learn a great deal about who is calling, just as we do when we answer the telephone. With so many variables at play, no two neighbours sound quite the same.

Even for humans, telling individuals apart by ear is often surprisingly easy. If Tawny Owls made long distance phone calls like us, their local accents would be very noticeable to their listeners.

Each habitat has its own acoustics, requiring slightly different hoots. In dense woodlands for example, lower-pitched hoots are better able to penetrate the many obstacles present. Open habitats permit higher-pitched hoots, but if conditions are windy then a lower pitch may be better.

Galeotti et al found the lowest-pitched Tawny in a karst region in Italy with very dense brushwood, subject to strong east winds. Even the female, heard from time to time just after the male, seems unusually low-pitched.

During the last ice age, Tawny Owls in Europe retreated to three different refuges where there was still suitable habitat. From their Balkan refuge they later spread to Britain, northern Europe and eastern Europe, from Italy they went north as far as southern France, while those that had survived in Iberia made it no further than the Pyrenees Brito There is evidence that at least two of these lineages developed slightly different hoots. Compound hoots from England have a more arched first note and a longer second note than hoots from northern Italy Galeotti et al A fourth lineage, S a wilkonskii breeding in the Caucasus and south of the Caspian Sea, is more distantly related Brito The Armenian male in CD is one of only a handful that have ever been sound recorded.

Compound hooting of a male, with occasional contributions from a female. Another male hoots in the distance. Hooting of a male, with another calling in the distance.

Female Tawny Owls also hoot CD , although in spring they often give just one or two strophes when the male delivers prey. They hoot much more intensively in autumn. One reason why female compound hoots are so variable is because of the highly charged situations in which they occur. In fact, female compound hooting is only really equivalent to more excited variants of male compound hooting. Males also give more variable hoots when excited, but rarely have more than one middle note.

In close contact with females they often shorten the gaps, both within and between strophes, and in territorial disputes their timbre may become harsh and whining. Sometimes, either sex may hoot just the first note of a compound hoot cf, CD Compound hooting of a female, responding to her mate in the distance.

At , the male gives an excited compound hoot with more than one short note in the middle, just before copulation. This is unusual and only happens at moments of high excitement. The timbre is slightly harsh, although this may only be evident at close range. During the breeding season, the female will often solicit for up to a minute or longer when she knows that the male is near the nest. Males can go for long periods without using the soliciting call, especially during the breeding season.
