Aqui seguen mas alguns dados, para esclarecer:
-----------------------------------------------------------------------------------------------------------------------------------------------
-EN VUELO HORIZONTAL (Y AR CALMO, ESPECIALMENTE SIN CORRENTE ASCENDENTES. ESTES VALORES SON DIFICILMENTE SUPERABLES):
Peregrino: 70 - 80 km/h, un Gerifalte hembra algo más. Esmerejon/Merlin: 60 km/h. Alguns Patos: más de 90 km/h.
-----------------------------------------------------------------------------------------------------------------------------------------------
IN A STOOP/PICADO, IN ACCURATE MEASURE, SO FAR (HASTA EL MOMENTO, PERO, EN PRINCIPIO, ESTOS VALORES PUEDEN SER SIGNIFICATIVAMENTE EXCEDIDOS, CON EXCEPCION DE LOS PASSERINES):

Abstract
Two stoops of Peregrine Falcons and two of Barbary Falcons were measured with a tracking radar. For the Peregrine Falcons, total altitude losses while diving were 250 m and 350 m. Steepest diving angles amounted to 42° and 40°, respectively. Maximal air speeds of 36 and 51 m/s (130 and 184 km/h) were recorded. For the Barbary Falcons, the corresponding values are height losses of 173 m and 189 m, diving angles of 20° and 34°, and maximal air speeds of 42 and 44 m/s (150 and 158 km/h). The 51 m/s (184 km/h) of a Peregrine Falcon represents the highest air speed of a bird accurately measured so far.

-EN CASO DE LA HORIZONTAL, LAS VELOCIDADES PUEDEN SER ALTAMENTE MAYORES CON VIENTOS LIGERAMENTE ASCENDENTES (O, EQUIVALENTEMENTE, EN VUELO LIGERAMENTE DESCIENDENTE), COMO DIZ LA TEORIA, E CONFIRMADO EM https://www.researchgate.net/publication/227621013_Flight_characteristics_of_birds_1_RADAR_measurements_of_speeds.
-EN STOOP/PICADO: EN LO CASO DE LOS PASSERINES (cerca de 20g, o aun menos), LA VELOCIDADE CERCA DE 200KM/H ES TERMINAL, ES DECIR COINCIDE CON LA TEORICA (EN PICADO).
-EN CASO DE AVES MUCHO MAYORES, COMO HALCONES HASTA 2KG, LA VELOCIDADE TERMINAL (SI LA PLUMAGEM FOSSE SUFICENTEMENTE DURA PARA NO ABRIR/VIBRAR DURANTE LOS PICADOS) ES CALCULADA EM (http://jeb.biologists.org/content/201/3/403)(http://www.avibirds.com/pdf/S/Slechtvalk8.pdf)
(1998) Gliding flight: speed and acceleration of ideal falcons during diving and pull out: Varia, para Halcones com 500g-2.0kg, entre 320km/h y 400km/h, o aun entre 500km/h y 625 km/h.

La conservación es polémica. Ser contra la cetreria es tan correcto como matar águilas hace 50 años.
