… there’s hope.
I wasn’t sure what to expect when I arrived at the site. My previous visit was on the 2nd of January and since then the Eastern Barn Owl family has had to contend with some challenging weather, including the run of 40C plus days last week.
Global warming and extreme heat events are increasingly being shown to have adverse effects on hollow-dependent fauna, for example the Greater Glider, where elevated temperatures are driving habitat change and physiological stress on this beautiful and threatened arboreal mammal.
Barn Owls are a ‘taxonomically fluid’ group with a cosmopolitan distribution. Recent research is south-west Canada suggests that extreme events (heat, cold and rainfall) can impact on the breeding success of the Western Barn Owl Tyto alba.
I digress, but now some promising news.
At 9.15pm, about 30 minutes after sunset, one adult flew from near the nest tree followed by a second some minutes later. I couldn’t tell if they were roosting there or at another spot nearby. Around 9.45pm one of the pair arrived with a House Mouse, perched above the hollow for about a minute, then delivered the meal.
It is now 42 days since I first observed the adults visiting the nest with prey and I surmise that the eggs hatched around that time. The young owlets typically emerge from the hollow around 45-50 days after hatching, remaining in or near the site for a similar time period before independence.
Stay tuned.
