The slopes of Heaval behind Castlebay were still burning after dawn this morning.
Heather on the hills are bone dry from the prolonged easterly winds over recent days.
Flames were fanned whipped by the stiff breeze as islanders joined local firefighters in attempts to control the fast moving fire front.
Barra Coastguard Rescue Team and crew members from Barra RNLI lifeboat also turned out.
Griminish and Lochboisdale coastguard teams were ferried across from Uist to assist.
Western Isles MP Angus MacNeil tweeted: "Spent a couple of hours from 9pm tonight helping Fire Brigade, RNLI Coastguard etc & whoever else who was about, trying to prevent at least mile long front of fire to reach houses at Cuithir Barra. Firefighters over from Uist too. Barra tinder dry."

Emergency services are battling wild fires on Barra.
Three moorland blazes broke out at different times overnight and islanders joined local firefighters in attempts to control the advancing fire front.
The first was reported after 7.30pm last night, then another late on while the third was called in after 5.30am this morning.
One house was evacuated and fencing was damaged said the fire service.
Flames swept down the hillside, closely approaching the cluster of longhouses at Cuithir, in the north west of the island.
