Most efforts were prepared for to install camera on new nest, where they breed last summer. We also were prepared for to change technical solution, means to transmit video over 4G internet.
But nature had own plans and we did not install cam there, because new nest was also fallen from tree. Though ravens nest was fine, just 30m of old nest of year 2016. That old nest place with some repaired base was not touched by eagles, only few feathers under nest tree of 2017. So took all equipment away of that place and started to check some other nests in that region, if there is some alternative. Not every nest suits for cam, but there are couple of possible ones. They need to climb up and check suitability from the nest level. That will be done next time. One of those options is territory of Linda and Sulev (we do not know if they still breed there) we observed 2008-2013, but new nest about in height of 30 meters in forest near the bog.
Some changes therefore are needed to make in cam set and suitable weather chosen. Maybe some work is needed to do in darkness.
Urmas 28.janvārī, 2018. raksta:
Vakar mēs kopā ar Renno un Omaru devāmies pārtraukt ilgo neziņu par Uku un Annu. Viss tika sagatavots, lai uzstādītu kameru jaunā ligzdā, kur tie ligzdoja pagājušajā vasarā. Mēs arī bijām gatavi mainīt tehnisko risinājumu, līdzekļus, lai pārietu uz 4G internetu.
Bet dabai bija savi plāni, un mēs kameru neuzstādījām, jo nokritusi ir arī jaunā ligzda. Kaut gan kraukļa ligzda turās labi tikai 30m no vecās 2016. gada ērgļu ligzdas. Veco ligzdu, kurai izveidojām pamatu, ērgļi nav aiztikuši, ir tikai dažas spalvas zem ligzdas koka 2017. gadā. Noņēmām visu aparatūru un pārbaudījām citas ligzdas šajā reģionā, vai ir kāda alternatīva. Ne katra ligzda ir piemērota tiešraidei, bet tur ir vairākas iespējas. Jāuzkāpj un jāpārbauda koka piemērotība no ligzdas līmeņa. Tas tiks darīts nākamajā reizē. Viena no opcijām ir Lindas un Suleva teritorijā (ligzda, ko novērojām 2008.-2013. gados, mēs nezinām, vai viņi joprojām tur ligzdo), bet jaunā ligzda ir 30 metru augstumā mežā pie purva.
Tāpēc ir nepieciešamas daži sagatavošanās darbi un piemēroti laika apstākļi. Varbūt nepieciešams darbs tumsā.

That place has been not far ago raise out of sea bottom, therefore poor soil and no such big trees, yet. But I'm sure they build new nest somewhere close by if right time approaches.
LK forumieši domā, ka Anna un UKu varbūt ir par jaunu, lai mācētu celt ligzdu...
Urmas saka, sakarā ar augsto ūdens līmeni tajā vietā ir nabadzīga augsne un nav lielu koku. Bet viņš domā, viņi uzcels ligzdu kut kur tuvumā.
