08/30/2019 by Cattus Island County Park
Excessive calling observed as soon as an approach is attempted. There is a singular juvenile present on the nest, calling and looking directly at the observers. An attempt was made to observe the perch pole associated with this nest, and the chick quickly departed and did not return for the duration of the observation. This nest does not respond well to human observation or interaction.

08/01/2019 by Cattus Island County Park
Upon approach, there is one large adult in a nearby tree, very close to the blue trail. In the actual nest there are two individuals, both chicks, that remain silent upon approach. When an adult arrives in the vicinity one of the chicks begins calling aggressively, most likely begging for food to be brought in. This calling persists for the rest of the observation of this nest.

06/07/2019 by Cattus Island County Park
Female is possibly engaged in feeding young chicks. Male is perched in nearby dead tree on the left. The female is very agitated upon approach, so the observer is forced to observe from a distance.

One chick sits in the nest and is highly alarmed by the polaris. It calls very loudly upon approach and flies off after a few minutes. Adults are not seen or heard in the area.

07/20/2018 by Cattus Island County Park
Defensive and loud calling upon approach. Male flies off when in view, leaving one small chick in the nest alone. Chick presses itself down in the nest, but is large enough to see overtop. Male circles back and lands and observer decides to leave the nest for the time being

07/13/2018 by Cattus Island County Park
Female is present and again calls upon approach in a very defensive manner. One chick is small but clearly visible. male is not within sight, but one individual seems to respond to the female's calls as she makes them from far away.

06/22/2018 by Cattus Island County Park
Calling is noted upon approach, though the observer cannot see the nest at this point. Upon a clear line of vision, female osprey flies off quickly and makes loud, startled calls while soaring overhead. Observer retreats to vehicle and waits until calling is not observed. Observer remains still and quiet for an extended amount of time upon slow approach. One chick is observed to be moving around in the nest.

06/15/2018 by Cattus Island County Park
Confirmed male perched alone on the edge of the nest calling. His calls are higher pitched than normal, and drawn out for almost a minute each time. The observer suspects distress again from proximity, but upon retreat the calls continue at the same frequency.

06/08/2018 by Cattus Island County Park
Confirmed female sits in the nest. Calls are observed upon approach, for about three minutes. Female is possibly alarmed by the presence of the observer and ceases to call as soon as distance is created between the observer and the female and her nest. At a distance female is silent.

06/01/2018 by Cattus Island County Park
