SSSSSwwwwwainsonainsonainsonainsonainson’’’’’s s s s s Thrush Thrush Thrush Thrush Thrush (Catharusustulatus)

A song forsummer… Thename for theS w a i n s o n ’sThrush, inseveral FirstN a t i o n slanguages, is“SalmonberryBird” because it migrates north toarrive when these berries begin toripen. This is a shy relative of theAmerican Robin, with a brown backand spotted chest that is not easilyspotted in the forest. However, whenwalking the deep interior trails ofStanley Park, one of the mostconspicuous and lovely up-trillingsongs you’ll hear, is of thiscamouflaged troubadour.

Did you know?Did you know?Did you know?Did you know?Did you know?• The Swainson’s Thrush migratesas far south as Peru to spend itswinters.• It is in the same family as bluebirds.

SSSSSlug ~ lug ~ lug ~ lug ~ lug ~ specifically, the Banana Banana Banana Banana BananaSlug Slug Slug Slug Slug (Ariolimax columbianus)

Sink your sensory fingerpads softlyonto this critter! The banana slug isan invertebrate, which means it hasno skeleton either inside or out. Its softbody is even more sensational bybeing covered in a gooey slime. Whenyou only move 8 cm a minute, youbetter not rely on your speed to keepyou safe. The slime acts as a self-defense and tastes horrible topredators. An exception is theraccoon, which rolls the slug in dirt tosoak up its slime before eating it!

Slug slime also keeps the slug wetwhen summer rains are scarce. In fact,the slime absorbs water to keep the

slug constantly moist. Remember thiswhen you touch it and try to washyour hands off. This is one timewashing won’t help. Let it dry on yourhands, then simply roll it up into a balland voila – clean hands. How likely areyou to see a slug? Very likely – as thereis no other creature in our west coastforests that is more abundant thanthe Banana slug.

Did Did Did Did Did YYYYYou Know?ou Know?ou Know?ou Know?ou Know?• Banana Slugs are the secondlargest slugs in the world.• Slugs have an extra cavity, orbreathing hole, on the side of theirbody to increase skin available toabsorb oxygen.• Slugs are important for theecology of the forest . They aredecomposers, which means that theyhelp break down dead plants andanimals, and turn them into soil. Inthe process of eating, they also helpspread seeds and spores thatproduce new forest plants.

Eco Action - Shrinking our Ecological FootprintYour ecological footprint is much bigger than the print that you make with your step.An ecological footprint is how much space and resources you impact to survive.

(Maya Credico, Children’s Summer Programmer)

Following the first Invasive PlanCouncil (IPC) forum in January, severalrepresentatives from the GreaterVancouver/Lower Mainland areacame together in April under theauspices of the Stanley Park EcologySociety (SPES) to discuss issuessurrounding the development of alocal urban non-native invasivespecies action team.

The “First Ivy Conversation” as it wascalled, was spearheaded byAnnemarie De Andrade, PublicPrograms Manager for SPES andcoordinator of the Ivy Busters Program– a stewardship initiative to controlEnglish Ivy and other invasive plantspecies in Stanley Park.

The focus of this half-day workshopwas to bring together keyrepresentatives from a diverse arrayof conservation and agency/land useauthorities working on invasivespecies management in urban andrural environments on the mainland. These included:• Stanley Park Ecology Society• Langley Environmental PartnersSociety

• The Como Watershed Group• Mahon Park Stewardship Project• Campbell Valley Regional ParkAssociation• Vancouver Board of Parks andRecreation• Lighthouse Park PreservationSociety• Piroche Plants (Pitt Meadows)• UBC• GVRD• Pacific Spirit Park Society• Green Timbers Heritage Society• No Ivy League• Evergreen Foundation• River Works ( The VancouverAquarium)• Native Plants Society BCThe outcomes of this session haveled to greater collaboration amongstparticipants and the support to forman invasive species committee thatwould fill the gaps of the present IPCactivities in respect to the mainpopulation centers of the GeorgiaBasin on the east side of the Basin. The main objectives of the actionnetwork are to establish thenecessary network and partnershipinfrastructure to deal with the diverse

but often overlapping interests andissues surrounding non-nativeinvasive species management in theurban/rural context. The goal is tolook for opportunities to poolresources and ideally develop asustainable long-term supportnetwork to address invasive speciesissues on the local front in GreaterVancouver.

The next steps for the network(nicknamed the urban invasive SWATTeam!) is to work with the IPC toformalize a committee identity, moveforward on identifying and bringingtogether other potential participantsand partners to reduce duplication ofeffort, prioritize actions and needs andsecure the necessary resources to act.

Reducing your ecological footprint does not have to be difficult at all. In fact, thismonth’s tip is simple, delicious, and makes a big difference in the size of your impacton the environment. It is a fact that the largest contributor to the size of an ecologicalfootprint is fossil fuel consumption. In fact, people consume fossil fuels daily withouteven knowing it and that is where this tip comes into play. Food transport, especiallyof fruits and vegetables, uses a huge amount of fossil fuels during the process oftransportation. An easy way to reduce this is by shopping locally. As an ecologically -minded consumer, it is important you make a conscious effort to buy locally producedand farmed products. This food is often more fresh and flavourful because of thelack of time it takes to transport it from the area of origin to its destination, so try itfor yourself and see the difference shopping locally can make.

The West End of Vancouver has longbeen documented as one of Canada’smost densely human populated areas.And now, the same can be said for thedensity of Great Blue Herons. Thereare more than 160 nests in 24 trees inthe Stanley Park Heronry this year,doubling the total nest number of2004. In fact, there are now morenests in individual trees than the totalnumber of nests the heronry had ineach of the years between 1994 and2003. The reasons behind the heron’sattraction to the trees in front of thePark Board offices at 2099 BeachAvenue are speculative, but all arebased on the benefits of the location.Great Blue Herons have nested inStanley Park since at least 1911. Theherons have moved twice within thattime period. They relocated from theoriginal location near Brockton Pointto the area near the former Zoogrounds in 1977 and then to theircurrent location in 2001. There are norecords of herons using anotherlocation in the Lower Mainland for alonger period of time.

Equipped with a 2-meter wingspan,Stanley Park, for the herons, is a shortdistance from the feeding groundshorelines of Coal Harbour, theSeawall, Burrard Inlet, False Creek andaround the peninsula to the FraserRiver. Most of the adult herons’ timeis dedicated to hunting, as they try to

placate the “tikk-tikk” soundinghunger of their chicks. There areusually several chicks in each of thenests and they grow quickly, reachingtheir parent’s 1.5m height and 2kgweight in the approximately 10-12weeks that the chicks remain in theheronry after hatching. The vastmajority of the adult and juvenileherons then leave Stanley Park for thesurrounding areas and are solitary forthe remainder of the year.

The future of the heronry in StanleyPark is as mysterious as their currentboom.Heronry growth cycles are veryunpredictable and this year’s doublingin nest numbers was not anticipated.The number of nests of this speciesat risk could remain at the currentlevel or fluctuate considerably, ineither direction, in 2006. As hard itmay be to imagine while looking up atthe heronry this summer, there willbe a day, perhaps in a few years ordecades from now, when the heronswill have moved to a new location, andthe activity of the heronry outside thePark Board Offices will be left in thememories and stories of the tens ofthousands of people who lived, visitedor worked in the West End ofVancouver during the heron years.Did you know:Did you know:Did you know:Did you know:Did you know:Much of the white wash that coversthe trees below heron nests is“powder down” , a product of the chestfeathers used to clean excess oilsfrom the birds’ plumage.

The StanleyPark EcologySociety ismonitoring adozen baldeagle nests inthe City ofVancouver in2005. Eight ofthese nestsd e f i n i t e l yhave at leastone eaglet inthem whileanother twonests definitelyhave a pair ofeaglets ineach.

There are 4 nests located in StanleyPark as well as active Bald Eagle nestsin Kerrisdale, Dunbar, Strathcona,Point Grey, Burrard View, EastVancouver, near UBC and Kitsilano.Some of the nests are in traditionallocations, at the top of an evergreentree in forested areas. Others aredistinctly urban, overhanging aroadway or close to anentertainment venue. Several areeven close to residential streets andhomes.

Eaglets monitored in 2004 were fed abird-based diet, with plenty of gulls,crows and rock doves (pigeons) beingcaught by their parents and broughtto the nest. Other identified prey in2004 included large fish, CanadaGeese, Grey Squirrels, Pelagic andDouble-crested Cormorants andDungeness Crabs. Bald eagles arenotorious scavengers and may haveeither hunted or collected the corpsesof the above species. There were alsoseveral steak bones and roosterfeathers and bones found in thevicinity of a nest in Stanley Park.

I’m a bald eagle anda proud new parentliving high up in mynest with my littleones in the park.Every day thisspring, I’ve enjoyedwatching you like ahawk as dozens ofelementary schoolstudents hike through park programswith SPES’ School Programs Staff. Thekids always look excited and eager tolearn - and from my perch - I can seetheir eyes open wide in wonder whenthey squint up at our nest from below.The only problem is, Mia, that I havean eagle’s eye view of the photographsthat you use with the students andthey’re old, old old! You certainly don’thave any photos showing our goodside. And the pictures you show ofour prey are so faded that they lookwholly unappetizing! I can’t let theeaglets see these or they’ll never learnto hunt! Do you plan to do somethingabout this, or do I have to call myagent?

Signed, Concerned on the Bridle Trail

Dear Concerned,

You do have a good point. While ourschool program materials have allundergone a complete facelift in timefor spring, we are still desperatelyshort of good photographs. We simplydon’t have any images of the park’sflora or fauna that have been donatedwith specific permission for use inschool programs. So I’ll have to put itout to the readers to help us. I knowthat we have many eagerphotographers as part of ourreadership. Perhaps, just perhaps,they will be so kind as to donate clearimages to us for use in schoolprograms. Imagine the impact thesepictures might have, reachingthousands of little ones each year!Not only will children will be able tosee them, but teachers will be able to
