“…Trapping appeared to remove most of the Rainbow Lorikeet population, and cause most of the others to vacate the area. Trapping methods have also been effective elsewhere at reducing numbers of other invasive species of birds (Woolnough et al 2005;Grarock et al 2014;Linley et al 2017; but see Phillips et al 2012), and played a major role in the eradication of the Common Myna Acridotheres tristis from islands up to 219 ha in size (Canning 2011;Feare et al 2016).…”

The Eastern Rainbow Lorikeet Trichoglossus haematodus moluccanus recently became established in Tasmania.This study presents opportunistic observations of the species in Hobart from March 2007 to August 2018. During the first 6 years, flocks of more than four Rainbow Lorikeets were seldom seen. However, during the middle of 2013 larger flocks of up to 14 birds were observed repeatedly. Following this, five birds were trapped and removed in August 2013 and another four in May 2014. Thereafter, only five observations of more than a single Rainbow Lorikeet were made, suggesting that trapping may be effective at controlling their populations locally. However, following the trapping sessions, apparent hybrids between Rainbow Lorikeets and native Musk Lorikeets Glossopsitta concinna became more common and more diverse in appearance. Four morphotypes of hybrids were observed, with one of these almost certainly the result of interspecific mating in the wild. Rainbow Lorikeets and hybrids foraged predominantly from flowers of Swamp Gum Eucalyptus ovata and at bird-feeders. Hence, Rainbow Lorikeets could possibly have impacts on Musk Lorikeets through interbreeding and, if they become more common, on these and other species of birds through competition for nectar and pollen of eucalypts.

“…Thirteen wild common mynas (7 females and 6 males) were caught in the Auckland region of New Zealand in September 2020 (Austral spring) using handmade, PeeGee traps baited with dog food pellets (Linley et al, 2017). The birds were transported to the University of Auckland and housed inside a temperature‐controlled (23 o C ± 1 o C), restricted‐access lab.…”

The birds had access to two perches, ad libidum water, were fed dog food pellets once a day, and fruit or mealworms (Tenebrio molitor) twice a week.…”

Experimentally elevated corticosterone increases song output and complexity in common mynas

Vocalization is an important communication tool that can reflect many aspects of an individual's internal and external condition. This is especially true for birds. Previous research has shown that bird calls and songs change in response to a variety of potential stressors, although the extent and direction of the changes depend on the nature of the stressor and the environment. Circulating glucocorticoids, such as corticosterone, often increase in response to stressors and mediate some of the observed changes via alterations of the individual's physiological state. Acute elevations of corticosterone often occur as a physiological response to short‐term stressors; however, the effects of this elevation on adult vocalizations have not been well documented. Here, we experimentally elevated corticosterone at two different levels using a noninvasive method and examined the effects on the vocal communication of male and female adult common mynas (Acridotheres tristis). Corticosterone elevation temporarily increased song output and some measures of song complexity, while call output decreased. These effects were dosage dependent (higher corticosterone levels had a stronger effect), most evident 40 min after ingestion, and some vocal changes were sex‐specific. Future studies should investigate whether the changes in vocal performance due to elevated glucocorticoids have consequences for the birds' behavior, reproductive success, and survival.
