would like to study the Saunja bay fish fauna and compare it with fishes brought to WTE webcam nest - to analyze fish biomass, preference of WTE and also sizes of fishes etc.
Therefore we kindly ask You to register all food items which Uku or Anna will bring to the nest: fishes, birds and all other items.
So far there have been 9 food items and all have been fishes: 6-7 Prassius carps, 1 Pike, 1 Burbot and 0-1 Perch. ...

Usually while bringing the food it is visible and possible to identify. This is better to see from videos (one good frame in video is usually enough).
If You have opportunity to make videos about bringing the food/fish this is the greatest! Videos might be quite short because best look for fish is while bringing it to the nest. If not possible to make videos then pictures are also ok and if necessary we can check videos later from pontu archive (takes more time). Species of fishes will be checked by Marine Institute people so don´t hesitate to give species names to the fishes
We shall try to fulfill renno's wish and collect in this topic observations of the different food items that are brought to the nest during the season. The topic will be kept locked so that only one observation with preferably a few clear and representative pictures of each prey item with timing and other information will be posted here. For this purpose we shall pick some of the observations reported in the nest topic. If you don't take pictures then please post verbal reports with as accurate timing information as possible.
These verbal announcements of deliveries are also important because if the time of an event is known then pictures can be taken later from the Pontu recordings. Especially later in the season when eaglets have grown bigger the prey have a tendency of disappearing in seconds so vigilance and attention are required.

Both today´s fishes were Prussian carp/Carassius in latin Carassius gibelio and in estonian hõbekoger. First fish catched by Uku was about 1 kg.
Fish day before yeaterday was Burbot Lota lota in estonian luts - this fish is not easy to catch because living in the bottom of the bay. But Anna and Uku have very good fishing area close to their nest as you can see from the webcam
