Don't count your robins before they've hatched

It may be one of the most iconic and recognisable garden birds in Britain. With its long, spindly legs, hopping across lawns, pecking at seed and insects on the ground, perching on wall, fence, branch. That beautiful orangey red breast and olive brown back, big dark eyes. Everyone knows the robin. From bossing your feeders (for such a delicate looking bird it is actually the one that tends to rule the roost at the feeder in winter) to it’s confident, melodious song that is heard often well before sunrise and throughout the year. This cheeky bird adorns our Christmas cards as well as often being so confiding they will learn to take meal worms and sunflower hearts from the very tips of ones fingers. It is hard to believe they are disdained in other European countries (which I was shocked to hear from a friend who sent a Christmas card with a robin on to a friend in Denmark!). On these fair shores the robin remains a firm favourite even if it will defend its territory to the death. 

The beautiful robin

For me I love ringing and handling robins. Catching them and learning how to age them (sometimes not as straight forward as they first appear). I also love finding their nests. For a bird that is so ubiquitous their nests can sometimes be quite hard to find. Hidden in all sorts of places on trees, on banks, in a wall or hedgerow, or even more unusual places like a horses muzzle hanging from the back of a door on a shelf in a workshop. The small, delicate nest is made from moss and dead leaves, lined with hair and wool, sometimes so perfectly blending in with the rest of the tree trunk or hedge row. Here usually four or five small eggs ranging from off white with brown speckling to a reddish brown all over, are carefully laid and incubated. The naked blind chicks, with just a bit of almost fuzzy down hatch after a couple of weeks and barely fill the bottom of the nest, squirming over each other, huddling to keep warm as mum and dad begin the furious job of finding enough food to feed them all. The instinctive reaction to lift their heads, mouths wide open showing a bright yellow mouth (a perfect target for a parent in a rush) means that when one checks a nest this is often the heart melting sight they are greeted with. 

Within a couple more weeks they are huge, pretty much full size and filling the nest to bulging point. A careful peer in will now reveal bright eyes, alert and looking back. Time to be really careful. Very very soon the next visit reveals an empty nest, trodden down with poop around it revealing that the chicks have left. It lucky you may catch a glimpse of the brown speckled young in the surrounding trees still scrounging a couple of meals from mum and dad. Soon they will be fully independent and shortly begin a partial moult that will, for all intents and purposes, make them look like an adult. Only in the hand will an experienced ringer be able to tell if a bird hatched that year or the previous. And so the cycle will begin again, where possible birds will spread out and maintain a territory for the winter before looking to pair up and breed themselves the following year. 

One of the more unusual locations of a robin nest

Each year it is my pleasure and honour to find a couple of robin nests, to monitor them where possible from building to egg laying, hatching to fledging. Always they have been nests with four or five eggs. This year though, in the crook of a small stump of a tree, overhung with ivy, I found a nest that once more had five eggs. However a return visit revealed a surprise. Not five, but nine eggs sitting in the bottom of this perfect little nest! Never in all my years of nesting (which are not that many to be honest) have I seen a robin nest with nine eggs, but more than that neither have many of the more experienced nesters I work with! Whether this is just a particularly fecund female, or whether another female has come along and dumped her eggs into the nest to save making her own, I will never know. But the female was good. 

Nine eggs! (last one tucked out of sight)

A couple of visits revealed her sitting tight, and I would leave her be, others she would not be there but I could hear her scolding me in the surrounding leafy foliage, ticking above the rush of traffic beyond. I was unsure how many would hatch but the next visit revealed another pleasant surprise. Eight tiny, squirming chicks crammed in. But how many would survive? How many would mum and dad be able to feed. Only time would tell, but a few days later and all eight were still alive and growing, ready to be ringed. Each now marked with a unique metal ring. Whoever or however many do fledge and survive, if they are ever found again by another ringer or a member of the public I will be able to tell straight away they came from my little miracle nest.

It is worth saying here both Lee and I are qualified and experienced nest recorders and ringers. These chicks were safe during the whole process, which was quick and completed efficiently.

Dash to the coast

Across the country the nation collectively groaned as the weather forecasts came in. Summer it seems was coming to a very abrupt end with gales and heavy rain predicted from midweek and over the weekend. Only one select group of people were eyeing up the predictions with relish. Northerly, and easterly winds, even some rain, birders on the east coast were rubbing their hands together at the thought of masses of migrant, common and rare, crossing from the continent. More than one booked last minute time off work as they themselves migrated to the coast.

Ringers also pricked their ears up at the forecast, constantly monitoring the changing weekend conditions with the hope of some sort of break, or brief pause in the storm that might bring suitable conditions to try and catch some of those birds that had made it to the coast.

Saturday was looking a total wash out with heavy rain and strong wind forecast all day. Sunday though, now Sunday was looking good. It seemed a respite in the wind and rain was coming.

Friday night and the forecast although improving on Saturday afternoon was still suggesting that Sunday would be the day. Of course the British weather being the British weather meant a certain pair of ringers woke up (thankfully reasonably early) on Saturday morning to find calm overcast conditions! Perfect for ringing but we were an hour from the coast! A frantic morning of throwing everything in the car (ringing kit, camping kit, food, blankets, dogs stuff, dog!….) and we made a dash for the coast.

All ready for a weekend ringing at the coast

It was not too bad all things considered… nets were up and birds were being caught by 10:30ish. Before the rain and wind then settled in, over 110 birds were caught and ringed. Most being robins and blackcaps, all recently arrived, but a few brambling and song thrush added to the mix and a special treat of a yellow-browed warbler one of those more rarer migrants….

Large numbers of robins recently arrived on the coast

Along the coast the conditions on Sunday were challenging for birders, with squally showers and strong winds, but the odd interesting birds were turning up, not least a spattering of yellow-browed warblers and for us, a wonderful view of a great grey shrike…


Not a bad blustery weekend after all….

The first of the year

After ten days bouncing around the frothy blue waters of the Caribbean in sublime heat, it was more than a bit of a shock to the system to return to the icy cold of Norfolk. Hail storms, remnants of snow and it felt like winter's grip had not lessened in the time I had been away. Yet, there were signs that spring was at least on its way. Blackbirds, song thrush and dunnocks were all in full song. More and more patches of snow drops were unfurling their delicate petals, clustering together in splashes of brilliant white. Daffodils sprung up along the borders, adding yellow to the palette. After months of dull greens and browns, they bring a welcome breath of colour and hint of spring. 

The beauty of snow drops

The paths around Thetford, through its historic castle mound and along the swollen rivers, remained muddy. Barley's paws and tummy were splattered as we made our way along the trails. Passing a piece of ivy hanging over a crumbling wall, a robin flitted down and out. Its tail flicking. Something about this birds behaviour piqued my interest, the nester in me, having been in hibernation, stirred. I ducked under and there in my line of sight was a neatly woven nest tucked amongst the branches gripping the wall. 

The beautiful robin

The season had started, here was my first nest of the year. Three warm eggs, waiting for a couple more. A visit a few days later reveals four warm eggs. For the next few weeks the progress of this individual nest will be monitored. The eggs, chicks and outcome recorded. Although one nest, it is hopefully the first of many I might find this year, and its record will be added to a national database, from which any number of questions can be answered.
