The 2nd Annual MaMu Day is happening on Sunday July 12th, 2026 in the unprotected Central Walbran Valley. Held with gratitude on Pacheedaht Nation Territory.
Come witness and celebrate the threatened seabird the Marbled Murrelet (MaMu). This event is a chance to hear and possibly observe the birds in the early morning as they fly from the ocean to feed their young high in their nesting grounds in the trees of the Old Growth Forest.
The MaMu is one of Canadas most endangered birds, its extraordinary life joins the ocean and the forest together, its continued survival relies on these remaining ancient forests and the efforts to protect them. This is an educational event to hopefully inspire action and imagination to work towards the birds protection.
This location and the date have been chosen as it is the height of nesting season. In 2024 there were 438 calls detected on an Automated Recording Unit (ARU) on that single day.
MaMu Day Schedule.
Early morning alert; The best time for observing starts at predawn, 4.00am until 6.30am.
Saturday July 11th.
Travel to the Central Walbran. Ride sharing and convoying will be available.
Noon. Camping options and preparing event area.
6pm. Opening circle. Talks by Dr Royann Petrell and the Wilderness Committees Toby Neame.
Camping; there is a choice to camp closer to the observing spots or at the camp sites near to the Walbran Bridge and then drive in on the morning. The latter option requires driving to the observation spot at 3.30am to be ready to start listening at 4.00am.
Sunday July 12th, MaMu Day.
3.30-4.00am. Meet in the observing spots. Bring a chair, blankets, dress warm, bug spray, hot drinks. Use cell phones or other devices to record and photograph the birds as it is possible to see MaMu later in the morning when the light improves.
6.30am Observing ends……
Notes;
Please this is a no social media event as we will be in a wilderness area and we do not have the capability to deal with a large gathering. If you are inspired bring your MaMu themed art to the forest on July 11th-12th and share your creativity. The Central Walbran has extensive trails, camp sites, outhouses and a visitor centre maintained by the Friends of Carmanah Walbran since 2012. Be advised this is a remote wilderness area, with rough unmaintained roads and without cell service. The location may change depending on conditions, updates will be posted on the group website. Please contact FoCW if you require more info and to pre-register; friendsofcarmanahwalbran@gmail.com
MARBLED MURRELET
(Brachyramphus marmoratus)
The endangered seabird the Marbled Murrelets is an iconic species for the West Coast and the Walbran Valley in particular. Biologist Dr Alan Burger’s work there in the early 1990s located the first MaMu ‘nest’ in Canada and identified the valley as a hotspot for the nesting birds population.
Recent studies there using Automatic Recording Units (ARU) have again confirmed the Central and Upper Walbran as having high numbers of Murrelets, with one device recording 438 calls on a single day, July 12th 2024.
To support the continuing legal and scientific efforts that are working for the birds protection this date has evolved into MaMu Day.The first event was held in the Central Walbran in 2025 and was supported by over 20 attendees.
As migratory birds nests are protected by Canadian federal law. A recent court case in Vancouver has challenged the narrow definition of the term “nest” in regards to protecting habitat. The case argues that the nests of these birds are in fact the whole tree and by association must include the forest the surrounds it. Old Growth Forests and the MaMu’s survival are the same.
MaMu are listed as Threatened (2017) by the Committee on the Status of Endangered Wildlife in Canada and in Schedule 1 of the Species At Risk Act. This is primarily due to loss of nesting habitat caused by extensive logging. The fragmentation of remaining forests also has a negative impact creating ‘hard edges’ that allow easier predation and disturbance on potential nest sites.
The Walbran/Kaxi:ks is a refuguim and supports one of the highest densities of nesting Murrelets known in British Columbia and anywhere south of Alaska.
Description:
- A diving sea bird, a member of the Auk family.
- Breeding adult is dark above, heavily mottled/marbled below, 25cm(10”) in length.
- Call is a series of loud high “keer” notes, a “seabird call in the forest”.
- Flies with rapid shallow wing beats up to speeds of 120 km/h.
The Marbled Murrelet is Old Growth Forest dependent, requiring the shelter of contiguous forest stands with trees of 200+ years with large mossy branches. A single pale greenish egg is laid in these nesting grounds and raised between mid-May and August. Once fledged the young birds first flight must make it to the ocean waters and its waiting parents.
The first MaMu nest in Canada was found in the Walbran Valley in 1990. Further studies have confirmed the valley as a hotspot for the nesting birds population. In Alaska populations have ‘declined about 70% in the past twenty five years….with similar declines’ in BC.’ In 2013 there was an estimated total number of only ‘358,000-418,000′ birds. (Ruth, 2013)
Since 2007 funding to universities for independent research on Marbled Murrelets has ceased with very little research currently focused on their nesting habitat. Under the current BC Government responsibility for managing Marbled Murrelet habitat is given almost entirely to the forest companies. (Burger & Chatwin, 2014, various papers)
