Management of Interspecies Interactions in Captivity

Introduction

This blog post is aimed to provide some useful information regarding the potential need for the management of interspecies interactions between different corvid species in captivity. We are frequently being asked, mostly by rehabbers and rescue centres, if and how certain corvid species can be kept together in an aviary environment. This question often becomes of interest due to a reoccurring problem in wildlife rescue and rehabilitation – the lack of available aviary space.

To shed some light onto this topic, one has to consider two different main scenarios. If and how different corvid species can and should be kept together depends on the set goal to be achieved, as there are different considerations to be made. The two main scenarios are rescue, rehabilitation and release opposed to long-term care in a sanctuary like environment. We will discuss and examen both scenarios in this blogpost.

Cats, Cars And Wildlife (Republished)

Editor’s note: This post has originally been posted on 29th May 2018, and has now been updated and republished.

What have cats, cars and wildlife in common? Cats are domesticated companion animals, cars are machines built by humans, and both are able to kill sentient beings when not supervised or controlled. Cars can kill cats and wildlife, and cats can kill wildlife too. Neither of both scenarios is ‘natural’, both are artificial and creations of humans. So what is the impact, and what can be done to keep both, our beloved companion cats and wildlife, safe?

Identification of Juvenile Rooks and Carrion Crows

It is usually not difficult to differentiate between adult rooks (Corvus frugilegus) and carrion crows (Corvus corone). Both species may look similar at the first glance, because both have black feathers that can also look glossy. However, the long pale and pointy beak, with bare skin around its base, is the most striking and characteristic feature of rooks. It is also worth knowing that rooks nest collectively in tall trees, often close to farms or villages, which are known as rookeries. In contrast, carrion crows are fairly solitary and are usually found alone or in pairs, although they may form occasional non-breeding flocks. Unlike rooks, carrion crows do nest solitary, maintaining a large breeding territory centred around the nest.

First Aid for Birds

Goldcrests 'The Seven Dwarfs'

Spring is approaching, and this means that this year’s nesting season is about to start too. At this time of the year birds start building their nests, flitting to and from their nesting sites in search of nesting materials. Nesting behaviour and success are affected by weather and climate. And so it is no surprise that climate change is also having an impact on our native birds, leading to an even earlier start of the breeding season, which is causing the ecosystem to become unbalanced. Due to these changes, hatchlings and nestlings are potentially at risk of starvation, if their food sources, like for example insects or sand eel, are not emerging at the right time or near the place of nesting.
