Ok, I’m a little behind the times. Last year a pair of Merlins arrived in the neighborhood. This April they returned ! There is a rather tall dead tree at the end of our block which they like to use as a perch, in the beginning of the season anyway. Now in early June I only hear them infrequently so I’m guessing that they found a nesting spot a little further away. Merlins are small falcons and having a raptor in the area makes it feel a little bit more wild ! Better pictures and recordings can be found here : Dendroica.
