bird - most likely of the Dove family. It could possibly be a sparrow though but whether it's unladen, European or African remains a mystery.

IMO, it looks like a bird in flight, with its wings along the side of the body. There is some motion blur, which can be seen easily by looking at other objects in the photos. Nothing in the photo is crisp and clear.
Usually when people make the claim "I never saw it when the photo was taken" is because it is a bird flying by quickly.
For comparison purposes:

A Pixel-Weighting Method for Discriminating Objects of Different Sizes in an Image Captured from a Single Camera

Summary: A novel method of pixel-weighting is proposed to calculate the size of a detected object in an image captured using a single camera. The calculated object size does not vary significantly regardless of the location of the object in an image, which allows it to be effectively utilized in a vision-based surveillance sensing algorithm as a meaningful feature for discriminating human intruders from other objects. Experimental results show the feasibility of the proposed method.
It ls not perfect but the size of the object compared to it's so roundings and the distances to other objects just say that it is bigger than a bird.
As to what I don't know!
A home intelligent service robot for recognizing a user and following the motion of a user and a method thereof are provided. The home intelligent service robot includes a driver, a vision processor, and a robot controller. The driver moves an intelligent service robot according to an input moving instruction. The vision processor captures images through at least two or more cameras in response to a capturing instruction for following a target object, minimizes the information amount of the captured image, and discriminates objects in the image into the target object and obstacles. The robot controller provides the capturing instruction for following the target object in a direction of collecting instruction information to the vision processor when the instruction information is collected from outside, and controls the intelligent service robot to follow and move the target object while avoiding obstacles based on the discriminating information from the vision processor.

2. The intelligent service robot according to claim 1, wherein the vision processor includes:a stereo camera unit for collecting image information captured from the camera;an input image preprocessor for correcting the image information by performing an image preprocess on the collected image information from the stereo camera unit through a predetermined image processing scheme;a stereo matching unit for creating a disparity map by matching corresponding regions in the corrected images as one image; andan image postprocessor for discriminating different objects based on the disparity map after removing noise of the disparity map, extracting outlines of the discriminated objects using edge information of an original image, and identifying the target object and the obstacle based on the extracted outlines.

Yes -- I agree it could be done with 2 cameras. Two points of view are required for depth perception. One camera is not enough to discern distance.
