One clash, two photos— Red-winged Blackbird Harrassing Great Blue Heron on banks of Francis Short Pond. In the first, the blackbird passes by the heron. In the second, the heron seems to me more worried. Once again two species clash, and once again the smaller seems to have the upper hand— or at least it took the initiative in this confrontational episode by dive-bombing the larger.
These photos were actually taken in 2019 shortly after I purchased my first DSLR, the camera I am still using—Canon EOS Rebel t7i.
