Breeding habitat loss linked to declines in Rufous Hummingbirds
Hello,
Thought this about rufous hummingbird declines would be of interest to some on this list.

How wildfire mobilizes mercury, exposing riparian birds and invertebrates to a toxin.
¡°Scientists are still learning about the various pathways mercury can take as it cycles between the atmosphere, land, and water. Wildfires are an important pathway because when forests burn,
the mercury sequestered in the trees and soils can be released into the atmosphere or washed into waterways in ash and destabilized post-fire soils. Once released, the mercury may encounter conditions where it can be converted into methylmercury and pose a
hazard to wildlife and humans.¡±

Iona Insect and Bird Monitoring Study
Hello, I wanted to share the interesting results of our Birds Canada study in Iona from last year (insect monitoring and bird data analyses), thanks to the group of students from UBC who analyzed the data. Please find attached their Executive Summary (3 pictures). Based on this study, students provided management recommendations to minimize disturbance of the Aerial Insectivore bird community, as the upgrades to the Iona Island Wastewater Treatment Plant are ongoing. We are hoping to resume insect and bird monitoring next year, as well as nest box monitoring and Tree Swallow tagging, so stay tuned!

City Nature Challenge just over a Day away!
Just a reminder that the global City Nature Challenge starts Friday! It¡¯s looking to be a bit of a damp one this year (for Metro Vancouver anyway). I recognize many birding folks
use eBird, but if you use iNaturalist as well and happen to be in Surrey Friday-Monday feel free to add to our local count. We're also part of a Metro Vancouver Regional-wide project this year. Participating cities can also use help with ID'ing observations
on iNaturalist from April 30 - May 5.
Further info
,? and the Metro project page journal for specific events.

Would love to see that Oriental Turtle-dove get included this weekend, would make for a unique observation to report in the international results!

¡®You can¡¯t love something that isn¡¯t there¡¯: readers on how the sounds of nature have changed around them | Environment | The Guardian
The sounds of silence around the world: anecdotal yet scary. Also I¡¯ve noticed being back in southeast Vancouver Island the past 4 years after over 30 years away (as a resident) that many local bird species have declined in sheer numbers. Only a few have increased (eg vultures in summer). Lately when I drive along the local highways for 10-30 km I hardly see any birds, except crows/ravens & sometimes starlings. I play a game with my 8 yr old son to get a prize for the 1st bird that one of us sees. We can often drive for 10 km or more before seeing anything. I wonder what it¡¯ll be like when he¡¯s a senior around here (& I¡¯m long gone). I¡¯ve been a birder for over 50 yrs, have been involved in wildlife mgt & taught for over 15 yrs in universities, including ornithology at UBC Okanagan 2 yrs ago. I have several publications on seabirds, estuaries, sense of place & sustainability. Plus I¡¯ve been the organizer for the Ladysmith Xmas Bird Count for the past 4 yrs. So U think that I have some expertise in this area of concern. A lot of posts on these sites involve chasing rarities. However, there¡¯s more for us all to consider than a few oddities showing up in our neighborhoods.
Bob Hay Cassidy, BC
ps I saw the recent post about birdlife comeback around Wellington, NZ: a great initiative to have sanctuaries & control feral predators. But there¡¯s much more to do globally, such as restricting neonicotinoids in agricultural applications. Otherwise the decline in nature sounds & birds will make us all the poorer.

There has been a lot of focus on window strikes and migratory birds but birds that winter in Southwestern BC are exposed to mortality due to window collisions and other human related threats such as predation by cats, for at least half of their annual life cycle and birds like Varied thrushes are particularly vulnerable.
