BIRD MIGRATION AND AREAS WITH SENSITIVE FAUNA

1 IP SWITZERLND ENR ENR 5.6 BIRD MIGRTION ND RES WITH SENSITIVE FUN 1. Concentrations The breeding or resting birds in Switzerland spend only a very low fraction of their time up in the air; flights are fairly low. The birds may be a risk for CFT when flying to roosting and feeding places and when transferring to other lakes. In general, the farther the birds fly the higher they climb, so the highest risk of reaching CFT FLT LTs could be far from the indicated concentration areas. For reports on bird observations, see GEN Migration Mass migrations occur mainly under tail wind conditions. The same rule is valid for the greatest flight heights. Low pressure areas induce lower flying (also in tail wind). 9% of migrations in Switzerland are a broad front migration of small birds, covering all the lower parts of the country, concentrated in valleys and passes under cyclonic conditions and in head winds. Under anticyclonic conditions, when flights are high, even the Jura and the lps are affected by this broad front migration. Yet it seems that some concentrations above valleys and passes are still present. Many birds, especially large day migrants, avoid to crossing large mountain and water areas and so may (even in fine weather) concentrate along certain topographic lines. There is practically no period during the year in which there is no migration. Day migration is heavier in the colder seasons, and night migration is more prominent in the warmer seasons. The movements of rooks (and in a comparable way those of pigeons and common buzzards) is most frequent in OCT. 3. Collisions with birds of prey in the lps In the lps, as in the lowlands, birds of prey may climb fairly high on updraughts and occasional collisions with CFT may happen. Single strikes with golden eagles show that these large birds of prey may also, as an exception, actively attack an CFT. So there is some risk in spite of the relatively low number of breeding pairs in the Swiss lps (about 3 pairs). Soaring eagles on thermal updraughts usually show a pronounced indifference to CFT. Somewhat more aggressive behaviour seems to occur in the case of pairs in sexual display (undulating flights: changing phases of upward spirals, diving and gliding). Flight display may occur in every season, most pronounced from JN to MY, and somewhat less in autumn after the fledging of the young. n attack may possibly be instigated by a direct flight of an CFT towards the pair at the same or a slightly lower level, or by coming within a critical DIST, of PRX m, of the pair. Intraspecific flights occur particularly in the vicinity of the nest, suggesting that the pilot should also keep in mind this possible danger. Most of the nesting sites are at LTs of to 2 m (lower than the preferred hunting area), at the slopes of large valleys or the exit of small valleys, usually in the upper part of steep rocky walls with free approach. 4. Overflying of offical sanctuaries for silence and nature Sanctuaries for silence and nature are areas of defined dimensions where antrophogenic (man-made) noise sources have been suppressed to a MNM level. The aim of such sanctuaries is a preservation of the diversity of natural sounds and silence for human recreation. Sanctuaries for silence and nature are depicted as "Zones to be avoided" on aeronautical charts and shall be avoided or overflown by motorised CFT considerably above the MNM FLT LTs in in accordance with Implementing Regulation (EU) 923/212 (Standardised European Rules of the ir), rt. 55 letter f and by taking the shortest possible FLT path. reas Lateral limits COORD WGS84 Nationalpark N E N E N 26 E N E N 25 5 E N E N E N E N E N E N E N 29 4 E N 29 4 E N E N 28 4 E N E N E N E N 2 59 E N E N E N 16 6 E N E N E N E N E N E N 8 18 E N 6 9 E N 6 4 E N 4 41 E N 3 4 E N 2 14 E N 2 27 E N 4 28 E N 7 25 E N 6 54 E N 7 52 E N 9 6 E N 11 2 E N E N 2 2 E N E N E SKYGUIDE, CH-862 WNGEN BEI DUBENDORF MDT
