Woodcock survey results
Annual roding counts: 2003-2021
Thanks to a growing group of dedicated volunteers, we now have good data on the number of roding Woodcock for up to 150 sites across 24 counties since 2003.
It is possible that weather has an influence on annual fluctuations in Woodcock numbers.
- Heavy rain and low temperatures in April and early May might result in higher chick mortality.
- In winter, low temperatures and lying snow will reduce food accessibility and could increase woodcock mortality.
Given the general declining trend, which may involve factors in addition to weather, it is essential that we continue to count at least 100 sites per year in order to monitor future change more closely.
Please do consider re-surveying your 2013 survey site or a new site this summer.
2013 Survey Results and Publications
Thanks to the help of our volunteers, over 800 randomly selected sites were surveyed in 2013, which has resulted in two papers being published using the data collected.
Changes in population size and distribution
The first paper examines the change in population size and distribution in 2013 and found:
- Breeding population estimate of 55,241 males - indicating a 29% decrease since 2003 (78,346 males)
- Woodcock were encountered at just one-third of the woodlands surveyed (Figure 2)
- Site occupancy declined by 19%, since 2003.
- Northern England, eastern England and Northern Scotland had the highest levels of occupancy (Figure 3)
- The lowest occupancy levels were in Wales and southwest England
- There was a severe decline in site occupancy of 21% in south Scotland
- There was an increase in site occupancy of 18% in northern England
- Occupied sites appear to be clustered around areas where large wooded areas remain, such as the New Forest, Thetford Forest, the Forest of Dean and Kielder Forest.
Breeding abundance, habitat and landscape
The second paper examines the influence of habitat and landscape upon breeding abundance and revealed:
- At large landscape scales, breeding abundance was correlated with the total woodland area and woodland type.
- Woodcock were more abundant in woods containing a varied mix of woodland habitat types and in woods further from urban areas.
- On a smaller spatial scale, Woodcock were less likely to be found at sites dominated by Beech and more likely to occur in woods containing Birch.
Counting birds and the Wetland Bird Survey (Tuesday 27 September, 10am)
This course involves one online session of about 1 hour 45 minutes, with a trainer:participant ratio of about 1:30. Participants' microphones are muted during the presentations but there is a large interactive component...
