Way back in 2005 I introduced some frog eggs into the garden pond. It was 2007 before we saw the fruits of that introduction – a single frog calling in the evening, with occasional sightings near the pond. Today, as I walked past the pond I noticed a little movement on one of the rocks, and, surprisingly, another wood frog in the pond! Whether this is a survivor from the first introduction or if some eggs slipped in unnoticed with other introductions to the pond in following years, I don’t know. It is possible it is a visitor from another garden pond nearby, but that is unlikely as we have no immediate neighbors with ponds. Regardless, it is a welcome addition to an urban pond and a good indicator of a healthy environment.
