Near the Cycling Path

There are several collection ponds in this newly developed, naturalized park near D and S's home. Many, many paths to follow. They came upon a loud group of magpies which were more concerned with their argument than with the intruders. (I wonder if a bunch of magpies is a murder of magpies. Or is that term exclusive to crows?) 
The extra is just wild roses which dot the route. These ones were not very fragrant...unusual.
