Article: This Hilarious Optical Illusion for Birds Could Save Your Life

https://gizmodo.com/this-hilarious-optical-illusion-for-birds-could-save-yo-1829716568

Paper: Wide-eyed glare scares raptors: From laboratory evidence to applied management

https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0204802


Both static and moving stimuli were used to scare the raptors, but only the looming eyes had the desired effect.
Image: M. Hausberger et al., 2018/PLoS One



a) test apparatus; b) birds (in percent) that reacted to the display of the visual stimulus. c) stimuli: LE: looming eyes, LTS: looming turning spiral (as used on some aircraft), LMS: looming moving spiral, LBD: looming black disc, FBD: static black disc, F Sph: static geometric shapes: sphere (depth impression), S: stripes (used for repelling birds from windows) [35], Fstar: static star, C control: grey screen. Chi-square test, * p < 0.05.; c) The stimulus displayed: LE: looming eyes, looming turning (LTS) versus moving (LMS) spiral, looming (LBD) versus static (FBD) black disc, static geometric shapes: sphere (F Sph), strips (S) static star (Fstar) and control (C).

Population trends for E. coqui and birds near the El Verde Field station. (A) Quasi-Poisson regression of estimated total number of E. coqui individuals against time from censuses conducted by Stewart (28) in the Activity Transect. (B) Quasi-Poisson regression of the estimated number of E. coqui individuals against MnMaxT during the time periods when Stewart's censuses were conducted. (C) Quasi-Poisson regression for the total number of birds captured during equal length, 4-d sessions of mist netting (31) near the El Verde Field Station against the period when the mist netting was conducted. (D) Quasi-Poisson regression of the total number of birds captured during Waide's (31) 4-d sessions vs. MnMaxT during the year of mist netting. The 95% confidence intervals are shown around the best-fit regression lines. Pr(χ) is the result of a likelihood-ratio χ2 test of whether the independent variable improves the model beyond an intercept-only model. P < 0.05 indicates a statistically significant regression.

Canada has some of the world's last wild places. Are we keeping our promise to protect them?

https://thenarwhal.ca/canada-has-some-of-the-worlds-last-wild-places-are-we-keeping-our-promise-to-protect-them/

Paper: Informing Canada's commitment to biodiversity conservation: A science-based framework to help guide protected areas designation through Target 1 and beyond

https://www.researchgate.net/publication/325125139_Informing_Canada's_commitment_to_biodiversity_conservation_A_science-based_framework_to_help_guide_protected_areas_designation_through_Target_1_and_beyond


Hotspots for Canadian protected areas identified in the research of Justine Coristine, Aerin Jacob and their colleagues. This map identifies hotspots in relation to Canada's historic land uses of urbanization, resource extraction and wilderness areas. The researchers use warm colours to "represent areas with the potential to make a greater contribution to reversing biodiversity decline and preserving biodiversity for future generations." Map: Coristine et al.


Note: Ontario's Polar Bear Provincial Park is a "Protected Area" and contains "Important Bird and Biodiversity Areas (IBAs)"
