Observation information

Individual information

If the bird is foraging, it would be really useful to have an estimate of prey intake rate. To do so, please try to record the number of prey that the bird swallows during one minute. You can repeat this as often as you want (the more, the better).

Group information

How many juvenile (1st year), subadult (2nd and 3rd year) and adult spoonbills are in the group? In case it is difficult to distinguish between juveniles (1st year)and subadults (2nd or 3rd year), then try to at least distinguish adults from immatures (as in the second picture (in the instructions pdf or on the website.

How do I recognize the transmitter?

Ornitela transmitter

How do I recognize juvenile, adult and subadult birds? 

Juvenile spoonbills can be recognized by their pale greyish bill and black wingtips. Photo: Peter Boers Adult birds have no black wingtips and a black bill with a distinct yellow tip. Subadult birds (2nd and 3rd year birds) have a darker bill than the juveniles, with a yellowish (but still vague) tip of the bill and often still black wingtips.
