Aquesta primavera va comen\u00e7ar sent molt seca, el mes de mar\u00e7 gaireb\u00e9 no ha plogut, per\u00f2 ara portem una setmaneta\u00a0 de pluges m\u00e9s o menys fortes i m\u00e9s o menys intermitents arreu del territori, aqu\u00ed i all\u00e0 plugims o ruixats.<\/p>\n

Nosaltres des del CdA ens agrada dir que “fem com els de Ridaura, que quan plou la deixem caure”; per\u00f2 el cert \u00e9s que davant d’una pluja forta ens trobem alumnes amb roba i cal\u00e7at inadequat i ens hem de plantejar si canviem l’activitat, fem alguna cosa a l’interior o ens arrisquem i sortim igualment.<\/p>\n

Aix\u00f2 \u00e9s el que ens va passar el proppassat dilluns amb els alumnes de 1r d’ESO de l’institut Neus Catal\u00e0, de Cornell\u00e0 de Llobregat. Arribaven als aiguamolls i el temps amena\u00e7ava pluja tot el dia. V\u00e0rem decidir fer igualment l’itinerari pel parc; cal dir que al mat\u00ed va aguantar i que a la tarda vam quedar xops com \u00e0necs. Per\u00f2 la pregunta inicial era: veurem ocells si plou? s’amaguen? surten per\u00f2 no volen? No hi ha una relaci\u00f3 clara sobre temps atmosf\u00e8ric i activitat dels ocells, per\u00f2 n’he trobat algunes pistes en un article de l’ornit\u00f2leg Abel Julien. Us en comparteixo quatre pinzellades:<\/span><\/p>\n

L’afectaci\u00f3 als diferents tipus d’ocells\u00a0 \u00e9s molt variable i una tempesta no \u00e9s el mateix per un passeriforme, un rapinyaire planador o, ja no diguem, una au marina.\u00a0<\/em>
\nUna majoria de passeriformes s\u00f3n migrants nocturns (excepcions, orenetes, merla, mallerengues) i tenen un front de migraci\u00f3 ampl\u00edssim. El cl\u00e0ssic mapa dels ocells passant per “autopistes” que es concentren a Gibraltar, estret del B\u00f2sfor i similars \u00e9s v\u00e0lid per aus planadores per\u00f2 no per migrants en vol actiu (passeriformes, enganyapastors, lim\u00edcoles, rapinyaires nocturns, p\u00edcids). Per tant, en una nit de primavera en l’\u00e8poca de m\u00e0xima activitat hi ha MILIONS d’ocells volant per sobre del mar Mediterrani. Si aquests ocells han sortit amb un cel clar, \u00e9s a dir, no plovia en el lloc on han decidit emprendre el vol cap a la posta de sol, i quan estan a alta mar es troben amb una tempesta els passa dues coses: una, la palmen com a mosques o dos, si el vent \u00e9s de llevant se’ls emporta cap a la costa (o aprofiten el vent per arribar-hi) i, tatxaaan… all\u00ed estem nosaltres!<\/em>
\nSi s’ha produ\u00eft el fenomen i ens han caigut molts ocells, a primera hora del mat\u00ed seran m\u00e9s localitzables perqu\u00e8 hauran anat a parar ves a saber on. Durant la resta del dia tindran temps per trobar llocs m\u00e9s arrecerats o tranquils i seran menys detectables. Si tenim sort i llavors plou o fa relativament mal temps durant uns dies, tots aquests ocells estaran sedimentats i podrem gaudir d’ells. Aix\u00f2 s\u00ed, a la primera nit clara i estable que faci, emprendran el vol cap al nord i ad\u00e9u…<\/em><\/p>\n

I tornant a la nostra visita de dilluns amb pluja als aiguamolls, podem dir que ens v\u00e0rem trobar en aquesta situaci\u00f3, que als ocells residents tot l’any i als nidificants estivals s’hi van afegir els Migrants Sedimentats a la Plana<\/strong>; per tot aix\u00f2, aquest dia de pluja a gran part del territori, v\u00e0rem poder observar molt\u00edssims ocells. Aqu\u00ed va una petita llista, agrupats per estatus:<\/p>\n\n\n\n\n\n\n\n\n
