will be such that all points of the studyarea come under direct observation, 

 including the interior of forests and the north shore of the river. The 

 species, location, sex hf known), age (adult or immature, if known), and 

 movements of each animal seen will be recorded precisely in relation to 

 habitat categories on field maps using colored pencil or ball point pen; 

 special notation shall be used to denote simultaneous observations and evi- 

 dence of territoriality (singing males, chasing, etc.). All vertebrates 

 seen, even those not identified, will be recorded; if not identified to spe- 

 cies, animals will be identified as precisely as possible: "unknown gull", 

 "unknown frog or toad," "unknown chipmunk," "unknown passerine," etc. 

 Starting points and direction of runs will be varied randomly to ensure that 

 all portions of the project area receive at least one day's early-morning 

 observation. The exact route taken, starting and ending points, and direction 

 of travel will be recorded directly on the field maps. Pertinent data re- 

 garding starting time, weather conditions, etc. will be recorded at the start 

 and end of each route on the field data sheets (a different set of maps and one 

 or more field data sheets will be used each day). Record time as military time 

 (e.g., 0820, 1916); use Beaufort wind speed code numbers. 



At the end of each day's run, the minimum estimate of the number of 

 animals of each species known to be present for each of two areas (the pro- 

 jectarea and the control area) and^ the total census area will be recorded on 

 field data sheets for each of the four sections of the map. (NOTE: If an animal 

 is seen in both areas (control and project), its will be assigned to the area 

 where first observed.) It is important that this analysis be performed immediately 

 after conclusion of each day's census run. Species will be listed in phylogenetic
