The reassurance of spring

Bee-eater (John Hawkins)

Conclusions of recent research on wildlife populations across Europe make for seriously depressing reading, especially for those of us with memories of what things were. Even in Extremadura, where the populations of larks and Corn Buntings appear still robust, my own notebooks carry testimony of the collapse of species such as Little Bustard and Montagu's Harrier. Rachel Carson's arresting image "Silent Spring" has been retrieved by journalists. And so I face this spring with anxiety, foreboding.

The rains only started at the end of February and to date we have already received  since then 86% of last year's entire total of rainfall total recorded in the immediate vicinity of our home. Whilst the landscape now looks luxuriously green, it was striking how the wetter and colder weather delayed flowering of many early species this year and how few butterflies were on the wing in the first half of spring. The result has been bittersweet: water resources have recovered, the middle spring plant growth looks set to be magnificent, but early breeding birds, especially raptors, have taken a big hit. Nest failure among the Griffon Vultures has been massive.

And yet for most of the migrant birds, the phenology of spring unfolds predictably. As I write I can hear a Nightingale singing in the garden. It arrived yesterday, pretty much on cue. This first week of April has seen the flood of Bee-eaters, creating a buzz of excitement in text messages and social media as, with extraordinary synchrony, people hear their heralding calls and catch glimpses of their bounding flight across the region and beyond. Notwithstanding our anxieties, the resilient return of migrant birds generates a sense of reassurance and relief. Whilst there are survivors, there is hope.

Black-eared Wheatear (Martin Kelsey)

I stood at one of my favourite places on the plains, jagged dog's teeth of rock erupting from the thin soil, which now has a green mantle becoming increasingly polka-dotted by colour, A newly arrived Black-eared Wheatear perched on one of these rocks, its quiet song interrupted only with periodic drops to the ground to snatch and pound a caterpillar. Its buff-sandy body spoke of deserts. Just a couple of metres away, a Northern Wheatear en route between the Sahel and the mountains of Central Europe had also paused. Looking in the other direction, I could see a male Little Bustard jerking its head backwards as it give its courtship call, while a small party of Great Bustard crossed the same field of view. Above them, a Roller sat on a wire and unseen Bee-eaters prrrted overhead. A pair of Stone Curlew stood hunched and morose, ignoring the zigzagging chases of rival Calandra Larks. All of this happening at the same time, in the same place, unscripted juztapositions. This too created a heady combination of emotions in me, as the observer: a sense of sheer good fortune, touched by the vitality of spring but underlaid with poignancy and nostalgia.
