This season’s numbers are <strong>the</strong> lowest in 5 years, but this is largely due to low<br />

figures from Gartmorn Dam where <strong>the</strong> previous regular counter has left <strong>the</strong><br />

district. If Gartmorn is excluded <strong>the</strong>n <strong>the</strong> o<strong>the</strong>r waters gave <strong>the</strong> best season<br />

ever. Whe<strong>the</strong>r <strong>the</strong>re has been a real relocation of birds needs to be checked in<br />

future seasons.<br />

Turning to individual sites, <strong>the</strong> top ten along with monthly averages are<br />

listed below:- (previous season’s figures in brackets)<br />

Site Average<br />

1. (2) Gart Complex 433 (366)<br />

2. (1) Gartmorn Dam 350 (996)<br />

3. (4) Lake of Menteith 319 (267)<br />

4. (3) Airthrey Loch 295 (279)<br />

5. (5) Loch Earn 265 (206)<br />

6. (7) Blairdrummond Park 189 (162)<br />

7. (12) Vale of Coustry 182 (124)<br />

8. (9) Doune Ponds 158 (149)<br />

9. (12) L. Dochart-Iubhair. 150 (155)<br />

10. (30) L. Watston 113 (52)<br />

The above table excludes sites where mallard are reared <strong>and</strong> released for<br />

shooting.<br />

With <strong>the</strong> striking exception of Gartmorn most sites show modest increases<br />

with Lake of Menteith having <strong>the</strong> best results for 16 years.<br />

Some indication of <strong>the</strong> degree of winter immigration by different species<br />

into <strong>the</strong> region can be got by comparing <strong>the</strong> September count as a percentage<br />

of <strong>the</strong> peak for that winter for each of <strong>the</strong> seasons 1997/8 <strong>and</strong> 1998/9. These<br />

figures are 74 % <strong>and</strong> 83 % for Mallard <strong>and</strong> 61 % <strong>and</strong> 87 % for Tufted Duck, both<br />

species with large Scottish breeding populations. However <strong>the</strong> September<br />

contribution for three ducks that are scarce breeders is much smaller – Wigeon<br />

5 % <strong>and</strong> 10 %, Pochard 10 % <strong>and</strong> 7 %, Goldeneye 0.5 % <strong>and</strong> 0 %. Teal scores at<br />

34 % & 23 %, this probably exaggerates <strong>the</strong> local bird contribution since <strong>the</strong>re<br />

is significant immigration in September.<br />

Linear Water Features: Rivers & Canals<br />

This season all of <strong>the</strong> canals in <strong>the</strong> region were counted but <strong>the</strong> river length<br />

decreased slightly from 118 to 104 km. Overall <strong>the</strong>re were on average 13.5 birds<br />

per Km.
