The emerging tail was the give-away. Yet, it was special to see these two as I have never seen an immature Bank Swallow before.
The two sat long enough for me to take a few pictures and to look up swallow pictures in my field guide. As this one stretches and readies to lift off, it is easy to see the distinctive white markings on the tail. When spread, these white markings looks like the adult.
Also, when sitting the notched tail looks much shorter than when in flight as seen before. Nevertheless, it still is quite short compared to the adult.
It is interesting as this is my third summer of birding. Up until this year, I was struggling with identifying so many different birds that I really couldn't handle dealing with immature-adult or spring-fall variations. Now, that I can identify more birds, I find that my depth of learning about each species is deepening. It has been quite enjoyable learning in this way - no pressure. After all, Rome wasn't built....
