An unseen Willow Warbler was "hooweet"-ing its way through the back garden this morningas I worked at the dining room table. I wondered if it was one of those lemony-yellow juveniles that are around at this time of the year. Later, a single House Martin flew over. This evening, a very agitated Wren possibly had a fledged brood in the Honeysuckle, judging by the squeaks emanating from there.
