April 23rd, 2021

2-3:30pm
54 degrees (feels like 48 degrees)
Partly cloudy (20-30% cloud cover)
17 mph wind coming from the West.
Area consists of a retention pond/residential/recreational (track fields, golf course, etc.)

This Friday it was very windy, making it difficult to hear bird calls. The birds we were frequently hearing were doing note after note of calls or songs, making it sound like one long string. We saw two Ruby-crowned Kinglets in two separate areas, but had very similar habitats. It was smaller clusters of trees surrounded by open areas (usually a field or golf course), or buildings. Habitat requirements often fluctuate from species to species, as it depends on what they feed on. One instance at the start of the Burlington rec path there was a Northern Cardinal constantly singing in a bush that was right next to the path, it could be defending a territory from a potential rival (we didn’t see another cardinal). The territory was very good as across the path there was a bird feeder which is very good if you are feeding chicks. This bird's fitness must be good as the song repertoire seemed to last for a couple of minutes before it eventually stopped. In the retention pond right next to the redstone lofts there was a pair of Canada Geese nesting there. We couldn’t see the nest but it was situated in the reeds, which I assume were patted down to make the nest. Other things that could be used are leaves, other plants, feathers, or potentially some ‘fluff’ that can come from trees when they begin to pollinate.

For my locator map the music notes represent how loud I could hear the call or noise. If it was a big note it means I heard it well, and a small note means I heard it barely at all. It was windy and there was a lot of noise at the golf course which made it hard to hear calls. Sounds seem to come from all locations, and exactly trying to find where the sounds were made it difficult. Luckily we could often see the birds so it made it easier to make them down.
