What our animals are up to this month… December 2020 Edition

November 29, 2020 by admin

By December, our native reptiles and amphibians should be dormant and sheltering somewhere warm for the winter. Unlike other animals which hibernate through winter, amphibians and reptiles do not undergo true hibernation; instead they enter a state of reduced activity.

Common lizards are one of the opportunistic species that make the most of mild winter weather by coming out of dormancy for brief foraging bouts. They will use these warmer spells to hunt for invertebrates such as worms, spiders and slugs before returning to their overwintering site. This behaviour is becoming more common as we are experiencing warmer winters.

You can encourage common lizards to your own garden by creating piles of rocks or logs for them to shelter in. Growing a variety of plants or building an insect hotel nearby will also attract a range of insects for common lizards to feed on, and they will appreciate having this food source on hand to take advantage of during the warm spells!

What our animals are doing this month… October 2020

September 23, 2020 by admin

October is truly a season of change for our native flora and fauna. As the temperature drops, vegetation starts to die back and our days get shorter, our native amphibians and reptiles start to get ready to face the challenge of winter.

Why is winter so challenging for our native Dragons?! Amphibians and reptiles are both ectotherms, meaning that they rely on external sources of body heat compared to endotherms, such as mammals, which are capable and dependent on internal generation of heat. This means that amphibians and reptiles have to find a way to navigate through the drop in external temperature, frozen watery homes, reduction in water oxygen levels and, often unforgiving, winter weather.

Each species has clever adaptions and behavioural changes that they go through each year between September and November for them to survive this wintery challenge.

It is a common misconsception that all amphibians and reptiles hibernate over winter, even though they will all be seeking hibernacula at a similar time, the type they need can differ from species to species as well as if they hibernate or overwinter. For example, the common lizard will be spending October feeding on invertebrates in preparation for winter before hibernating, often in groups, amongst rocks or dead wood.

Whereas, our newt species overwinter and go dormant under rocks or buried in mud, but take advantage of milder weather to forage.

By early October most of our reptile species will have entered their winter hibernation. The majority of the UKs reptile species will have favoured hibernating sites, such as the Adder who will return to their wintering sites that they use each year. With Adders often basking in the last of the autumnal sunshine until the end of October when they become dormant for the colder months.

Some species, particularly slow-worms, common lizards and grass snakes, will make use of piles of dead logs, leaves or compost for the winter. It is important that reptiles are not disturbed during their hibernation period since it takes them longer to recover if they have to become active.

An amazing way to help our fantastic amphibians and reptiles is to consider them when planning your wildlife garden. One of my favourite things to do is create a hibernaculum, an amazing space for all amphibians and reptiles to hunt, forage and of course over winter. They are so simple to do and can make such a difference! If you are short on space you could also make a ‘toad home’!

What our animals are up to this month… June 2020

May 29, 2020 by admin

June most likely sees the final time of the season for mating behaviour in two of our native lizards – the common lizard and the slow-worm. These behaviours will start being exhibited in late April. Both of these species’ males will fight as rivals if they encounter each other in breeding territories. Females will mate with multiple males over the course of the breeding season and, if observed, both species engage with a powerful bite and grasp that could be mistaken for fighting behaviour.

Mating behaviour in slow-worm is rarely observed with activity occurring underground or amongst thick vegetation for this reptile species which spends much time away from prying eyes! Females are known to breed every second year with breeding condition reached at a length of 28cm. The amount of mating in a season is dependent on the temperature across spring and early summer – with higher temperatures leading to increased mating activity. Males and females become entwined during breeding for a period of up to ten hours.

Common lizard mate on warm sunny days with males chasing receptive females. Studies show a male’s bigger body size is preferred in female’s mate selection strategies. Females are less selective with their first mate, after which they go ‘up the ladder’ with their selections, choosing males in better body condition.
