Having shot many thousands of bird images I'd say it is tough to convey the kind of emotion in bird photos as you might with say a cute young mammal or even a powerful adult mammal. There are exceptions like some shots of chicks or some bird interaction shots that might convey more emotion but a lot of bird photos don't grab the emotions in the same way many mammal shots might.
That said, there are many possible dimensions for good or even great wildlife images including all the normal photographic things like interesting light, good composition, the interaction of color, action, the sense of tranquility, intrigue or other aspects of working photos. From that standpoint I think you ticked a lot of boxes with these images that are: well composed, shot in nice light, have good connection to the subject (very good head positions especially in those first two bird shots giving good eye connection to the viewer) shot from good perspectives making the subject pop and the background recede, good background control in general and overall very nice images.
Keep putting in field time with birds and other critters and you'll get those high emotion shots when the subject does something really interesting but I'd say these shots work on a lot of levels.
