Carnivore/ sexual deceiver (probably)/ bird-fanciers: Wireless Hill, Spring 2022.

 

Each of the headline’s descriptors applies to one or more of this post’s species – all blooming a deal less than a kilometre away from both a large shopping centre and one of Perth’s arterial roads.

For just about any “exceptional”, “extreme”, or “weird” form of flowering plant behaviour, southwestern Australia is the global hotspot.

Birds, not bees: Wireless Hill, Spring 2022

 

Unsurprisingly, southwestern Western Australia produces many different honeys, each deliciously distinct.

The most prized varieties are produced from rare, endemic species.

However, Western Australia’s southwest also has the world’s highest proportion of flowering plants that do not feed and/or seduce/deceive insect pollinators; these flowers (all, endemic species) favour birds.

(a few rely also/instead on particular, very small, also-endemic mammals)

WA’s floral emblem is bird-adapted.

But birds are better than bees…

…at least if you are a Kangaroo Paw, seeking effective pollinators,

All Kangaroo Paw species primarily rely on birds; for them, bees are “useless”.

Kangaroo Paws are not alone in relying on vertebrate pollinators; in this respect, Australia’s southwest is the world leader.

And many West Australian plants that do rely on insect pollinators are “liars” – plants pretending to be “receptive” insects!

Spring: uncommonly brief, unusually early

The late September holiday weekend usually coincides with the peak of Perth’s annual springtime wildflower “explosion”.

Not in 2019: very low rainfall in August and September prompted many plants to flower early…or not at all.

At any time of year some things are in flower, but if you wish to experience Perth’s 2019 Spring wildflowers, head to places like this post’s destination very soon!
