Something we have returned to time and time again in The Bird Emergency is how we have removed the nesting opportunities for birds that require hollows, and the need for shelter by all sorts of wildlife. Thankfully, there are many people looking at other options, other than waiting 100 years or so for natural hollows to form. Dr. Kylie Soanes tells me about some of the options being explored in Melbourne, and some of the new materials being employed. Here's a link to a Pursuit article about Dan's fancy nest boxes that we were discussing; https://pursuit.unimelb.edu.au/articles/new-design-tech-offers-hope-for-urban-wildlife   and the paper itself, which is open access https://doi.org/10.1111/2041-210X.13806   Follow Kylie on Twitter here - https://twitter.com/kyliesoanes   Kylie is a bit of a rockstar on TikTok - https://www.tiktok.com/@drkyliesoanes   You can check out the work of Kylie's lab, School of Ecosystem and Forest Sciences , The University of Melbourne - www.lifeontheverge.com.au     You can watch many of the past conversations, and see the upsoming interviews live at thebirdemergency.com/live Subscribe to on The Bird Emergency on YouTube Follow The Bird Emergency on Twitter @birdemergency or Instagram @thebirdemergency  If you enjoy the show, how about share with your friends or colleagues?  https://followthepodcast.com/birdemergency Or you can review us at https://lovethepodcast.com/birdemergency And if you want to support what Grant is doing with the show, why not buy him a coffee?
