Marco contador de murciélagos BatCounter

Hoy nos hacemos eco de una novedad recogida en la sección de Bazar de la revista Quercus 361, de marzo de 2016.

  Desde Holanda llega un revolucionario aparato para contar murciélagos (o cualquier otro animal) que pase por el interior de un marco. El sistema es capaz de almacenar el número de pasadas en diferentes formatos de archivo mediante una tarjeta SD. También puede enviar un SMS o un correo electrónico (tarjeta SIM no incluida) que permite disponer de los resultados sin necesidad de acceder físicamente al BatCounter.
  El dispositivo se alimenta con 8 pilas AA y dispone de una conexión a una fuente de alimentación externa (12V) que permite periodos de estudio más largos. También es capaz de disparar una cámara réflex (Nikon o Canon) con un cable de extensión o mediante infrarrojos.
  El marco del BatCounter crea 32 barreras paralelas de infrarrojos que emiten un impulso cada vez que una o varias de ellas quedan cortadas por el paso de un objeto que mida, como mínimo, 25 milímetros. Hay dos modelos disponibles, uno estándar de 80 x 39 centímetros y otro más pequeño y manejable de 30 x 39 centímetros.
  Basta con colocar el BatCounter en la boca de una cueva, grieta, ventana o árbol, cuando los murciélagos entran o salen de la colonia, para que el dispositivo cuente todos los individuos que atraviesan el marco. También puede instalarse en la entrada de una madriguera o ante una caja nido. Sirve para contar todo tipo de animales.

Está a la venta en Oryx por 2.415 €, IVA incluido.

En la página 81 del Quercus de este mes, número 361, hay un par de fotos de los equipos en acción.

En esta mina de Dinamarca, Mønsted Limestone Caves, deben tener instalado uno, porque ofrecen unas gráficas automáticas de entradas y salidas de murciélagos, comparándolas con la temperatura.

En la página del fabricante, Apodemus, (que tiene muchísimos gadgets para murciélagos) hay algunos detalles más.




Modelo grande:

The BatCounter is an electronic device developed to use in field applications for counting bats, birds or other small animals passing through its rectangular or square shaped aluminium frame. 
The aluminium frame of the BatCounter has had a black anodized surface treatment that protects the BatCounter in the outdoor making it a rugged and reliable partner. 
When using the BatCounter for less than two days, you can rely on electrical power via the 8 AA batteries that are in the box. To enable longer runs, hook the BatCounter up to an external battery of 12V using the external power cable that is included. 
The BatCounter detects and counts the different passings of bats and stores all the information on the SD Card. Not only will the collected data be available on the SD Card, external communication of this data is possible. Reports stating results and default information can be send by email and or SMS text messages at set intervals. This additional feature will provide you with results without the need to be physically present at the site and it will give the reassurance that the system is operating smoothly on a constant basis. 
Simultaneously with detecting bats passing through its frame, the BatCounter is able to trigger your DSLR camera (Nikon or Canon) using an external cable or through infrared signal.
