After a report in April from a fellow Nightjarist in South Wales, BL made four very early visits,going to three sites on the Northern end of the Forest but having no luck. A site on the Eastside proved a better bet, with two males seen on May 2nd . Four males were reported fromthree sites … Read more
For the past 22 years, audio recordings of male songs in the Forest have been systematically studied, following up Margaret Rebbeck’s 1999 paper that suggested male Nightjar are individually distinct in the pulse rates and phrase lengths of their churring. The components of Nightjar song are described here and analysis of a sample looks at … Read more
The 2024 season began for BL on May 4th with a single male on a chilly evening at one of the GWT Reserves. This is a typical first date for the Forest. Not so typical this season were changes in both personnel (see below) and to some extent, locations. Some of our long-term favourite Nightjar … Read more
Our season started on May 7th, when BL visited sites G and AA and found singing males at both. May 10th is the average first report date for Gloucestershire, over the last twenty years. The same evening we were hearing reports from two other heath sites. Two weeks later, we were back at site G … Read more
In 2022, we came across a recording of a bird that sang for 18 minutes, 34 seconds continuously and suggested that this would be hard to beat. Turns out we were wrong about that; this year one of the AudioMoth recordings from site U showed a continuous burst of song that was an astonishing 34 … Read more
On May 25th we visited Site K, where there were reports of 2 males. At around 21:20 one of these birds started churring, some 100 metres away from us. About a minute later, a second male started up, much closer to our position. In the field, we immediately noticed an unusual effect in the second … Read more
Some things in life are even more important than nightjars. Once again, events conspired against the project this year with the result that as far as fieldwork was concerned, the team was reduced to just one person (BL) for large parts of the season. Regardless of the team size, the plan for this year had … Read more
We’ve been reviewing the data gathered by the first deployment of the AudioMoth recorders this season and came across this recording from site AO. Figure 1 shows the pattern of singing between 0300 and 0430 BST, which is the dawn window in which the devices have been configured to record. The longest gap between bouts … Read more
Already well into the 2022 season, we thought it was about time we wrote something about the 2021 season! The first bird of the 2021 season was on May 12th at site AF, where a male was seen in rainy conditions. Two nights later, there were 2 males seen at site AY, but the first … Read more
The history of the Nightjar in Gloucestershire reflects the national one; early records tell us that it was once widespread, that the species has endured a long decline throughout the twentieth century and has then had a modest recovery. Nationally, although overall numbers have recovered somewhat, its range is much contracted and this too is … Read more
