Zigzag (up-down-up-down or “M” pattern	Brewer’s Sparrow	House Wren Lesser Goldfinch Chipping Sparrow Lark Sparrow Yellow-rumped Warbler	Golden-crowned Sparrow	Savannah Sparrow
Plateau (increase from year 1 to year 2, no change since)	Sage Sparrow		Acorn Woodpecker Steller’s Jay California Thrasher White-breasted Nuthatch	Red-winged Blackbird

Not bold: Species whose pattern of change along the burned routes did not differ significantly from their pattern along the unburned routes. Though these species may have responded positively (column 2) or negatively (column 3) to the fire, their variations since the fire have not been affected clearly by postfire succession.

Bold: Species whose pattern of change along the burned routes differed significantly from their pattern along the unburned routes. Though these species may be about equally abundant in burned and unburned areas (column 1), their variations since the fire have been affected clearly by postfire succession.

Bold italic: Species whose pattern of change along the burned routes differed significantly from their pattern along the unburned routes because they were absent along the unburned routes or their numbers along the unburned routes were so low no comparison could be made.
